unitary construct definition psychology

Olfaction, navigation, and the origin of isocortex. official website and that any information you provide is encrypted For this reason, here we step away from the concept of attention and take a brief detour into the history of how the relevant neural circuits evolved in the lineage that leads to homo sapiens (humans). Towards a unitary approach to human action control. This emphasis on integrated sensori-cognitive-motor processes takes inspiration from the synthetic approach to understanding cognition (Hommel & Colzato, 2015) and a proposed phylogenetic refinement of the scientific approach to understanding behavior (Cisek, 2019 [this issue]). Cognitive endophenotypes of psychosis within dimension and diagnosis. unitary. Of particular relevance to the present purpose are behavioral studies revealing that perceptual discrimination at the goal location of an upcoming saccade is improved (Deubel & Schneider, 1996; Gersch, Kowler, & Dosher, 2004; Hoffman & Subramaniam, 1995; Peterson, Kramer, & Irwin, 2004). Interestingly, when decisions between positively and negatively rewarding stimuli are made rapidly (Chapman et al., 2015b), asymmetries in choice behavior are also observed, but go opposite to loss aversion. Cognitive Neuropsychology, 2, 211228. An argument-based approach to validity. Conscience vs. For example, sudden changes in consciousness might be a sign of: If you thinking you are experiencing changes in consciousness, talk to your doctor. For example, preparing for a grasping movement facilitates the detection of size oddballs, while preparing for a pointing movement facilitates the detection of location oddballs (Fagioli, Hommel, & Schubotz, 2007; see also Craighero, Fadiga, Rizzolatti, & Umilt, 1999). Deciding not to GO: Neuronal correlates of response selection in a GO/NOGO task in primate premotor and parietal cortex. Hence, establishing a bias for shape and orientation over color when grasping would be a functional adaptation. Gallivan, J. P., Barton, K. S., Chapman, C. S., Wolpert, D. M., & Flanagan, J. R. (2015). Hoffman, J. E., & Subramaniam, B. Indeed, prioritizing shape and orientation when grasping objects makes more sense than prioritizing color because those features are more likely to determine a successful or an unsuccessful grasp. This ever-shifting stream of thoughts can change dramatically from one moment to the next, but your experience of it seems smooth and effortless. We conclude that what would serve scientific progress best would be to drop the term attention as a label for a specific functional or neural system and instead focus on behaviorally relevant selection processes and the many systems that implement them. However, this is incorrect. Epub 2012 Feb 18. Di Lollo, V. (2018). As recent considerations suggest, however, the various types of memory may not at all reflect the operations of separable dedicated systems, but rather stand for different byproducts of normally functioning cognitive systems (Buckner & Schacter, 2004), and emerged at different times during the evolution of our species (Murray, Wise, & Graham, 2017). Once psychology was established as a discipline separate from philosophy and biology, the study of the conscious experience became one of the first topics studied by early psychologists. In S Schneider, M Velmans (Eds), The Blackwell Companion to Consciousness, Second Edition. This finding suggests that what participants take to be rewarding is itself multifaceted not just the magnitude of the reward, but also how likely it is that they will receive the reward. Other research has extended the study of these action-attention interactions to manual actions, showing that planning and performing reaching and grasping movements prioritizes the processing of the target objects of these movements (e.g., Pratt & Abrams, 1994; Rizzolati, Riggio, & Sheliga, 1994; Tipper, Lortie, & Baylis, 1992; see also Wu, 2014). Another common criticism is that multiple processes underlie what is typically labeled as attention (Di Lollo, 2018; Hommel & Colzato, 2015). The cortical motor system. As we show in the expanded discussion of these three points in the following paragraphs, all these assumptions are incorrect. Vision Research, 36, 1827-1837. Modern validity theory is considered unitary and can be traced back to Lee Cronbach. The principles of psychology. HHS Vulnerability Disclosure, Help 59-80): Springer, Berlin. Behavioral sciences use constructs such as conscientiousness, intelligence, political power, self-esteem, and group culture. It is still the standard model of how short-term memory works, and it will continue to be the standard model until new evidence overturns it. Cisek, P. (2007). Evolution of posterior parietal cortex and parietal-frontal networks for specific actions in primates. (2005). Snyder, L.H., Grieve, K.L., Brotchie, P., & Andersen, R.A. (1998). (2016). Language links are at the top of the page across from the title. https://doi.org/10.3389/fpsyg.2015.01435. It is this latter tectal sub-circuit that is most relevant to attention and selection. One such factor that is intertwined with selection history is reward history. Cutrell, E. B., & Marrocco, R. T. (2002). As a rule of thumb, we might consider a system monogamous if two of the three dimensions of monogamy are present. In view of a failure of this approach, as is obvious for the case of attention versus intention, two reactions are to be expected. A critical review of twenty-five years. For example, strong support for content validity inferences can be used to support claims concerning the construct that is being measured by the assessment device. Welsh, T.N., & Elliott, D. (2004). You must there are over 200,000 words in our free online dictionary, but you are looking for one thats only in the Merriam-Webster Unabridged Dictionary. In other situations, however, different fronto-parietal streams will be coordinated. The most prevalent criticism of the unitary models is that they try to oversimplify many complex processes into a single mechanism. Premotor and parietal cortex: corticocortical connectivity and combinatorial computations. government site. (2015). Taken together, these and other findings strongly suggest that selection history is tightly interconnected with reward history and that neither of these concepts are particularly well understood. However, many species that can be treated as "monogamous" may fail to show one or more of these characteristics. For When 'Lowdown Crook' Isn't Specific Enough. Kendra Cherry, MS,is the author of the "Everything Psychology Book (2nd Edition)"and has written thousands of articles on diverse psychology topics. (1999). (2001). Scherberger, H., & Andersen, R. A. We reaffirm these positions and further suggest that compartmentalizing attention and then searching for the attentional system hinders the development of a comprehensive understanding of human behavior because it ignores integrated, parallel, and reciprocal relationships among sensory, cognitive, and action processes. Epub 2018 Apr 23. Hove, England: Psychology Press. (1985). The component is episodic because it is assumed to bind information into a unitary episodic representation. No one knows what attention is. Instead, we suggest that a complete dismantling of the concept of attention is required. For example, very similar arguments to those that we present in the following have been put forward to question the concept of memory. Cerebral Cortex, 6, 102-119. Parietal association cortex in the primate: sensory mechanisms and behavioral modulations. Epub 2021 Aug 13. synonyms. It includes visual representation of the possible moves, and awareness of the flow of information into and out of memory, all stored for a limited amount of time.[4]. Kaas, J. H., & Stepniewska, I. It's a way of putting a name to things that don't . DE Meyer, S Kornblum, pp. (2013). Unitary Construction. The evolutionary history of spatial interaction along the primate lineage is a long and complex tale (Fig. Horm Behav. However, no single method or strategy can provide all the evidence needed to make accurate or confident inferences. Journal of Neurophysiology, 97, 3093-3108. For example, visually guided reaching actions involve the medial intraparietal cortex (Cui & Andersen, 2007; Kalaska & Crammond, 1995), which represents targets within reach with respect to the direction of gaze and the position of the hand (Buneo, Jarvis, Batista, & Andersen, 2002; Gallivan, Cavina-Pratesi, & Culham, 2009), and is interconnected with frontal regions controlling reaching, such as the dorsal premotor cortex (Johnson et al., 1996; Wise, Boussaoud, Johnson, & Caminiti, 1997). Visual neglect. Muller, J.R., Philiastides, M.G., & Newsome, W.T. Along the same lines, attention is considered by some to represent the critical capacity limitation, the cognitive bottleneck that needs to be accounted for and explained (e.g., Pashler & Johnston, 1998), while still others consider attention to be the cognitive means to deal with such bottlenecks (e.g., Bundesen, 1990). Jones, M. R., Grillner, S., & Robertson, B. On the other hand, Unitary Theories have more trouble explaining situations where short term memory differs such as the word length effect,[9] which can be more easily explained by the Working Memory model. Neuron, 56, 552-559. Mind, A Quarterly Review of Psychology of Philosophy, 43, 305-323. When an animal (including humans) is placed in a laboratory situation and trained/instructed to perform just one isolated aspect of complex natural behavior, what the researcher will observe in this region is activity that appears to be related to what the researcher has defined as attention, intention, or decision-making, depending on the particular task variables that are being experimentally manipulated. Friese, M., Loschelder, D.D., Gieseler, K., Frankenbach, J., & Inzlicht, M. (in press). (b) Spatial averaging of escape directions (numbered arrows) away from two threatening stimuli (black stars) is an effective response. Our work on voles, like that of Mason and his associates on primates, reveals important differences in the motivational systems of monogamous and nonmonogamous species. (2010). This critics the above model. The main reason why hybrid approaches that simply lump together different factors are not overly successful rests in the fact that the respective factors are not truly integrated into a coherent framework. CONSTRUCT VALIDITY: A UNITARY CONCEPT between the items and tasks and the definition of the construct being measured. On the other hand, however, we fully subscribe to the assumption that good theories in cognitive psychology and the cognitive neurosciences come from testable hypotheses of how an observed phenomenon (the explanandum) is produced by its underlying mechanisms (the explanans), irrespective of whether these mechanisms are described in neural or functional terms. A major advance occurred during the Cambrian epoch, over 500 million years ago (Mya), with the elaboration of visually guided orientation behaviors. Despite robust evidence of neurocognitive dysfunction in psychotic patients, the degree of similarity in cognitive architecture across psychotic disorders and among their respective first-degree relatives is not well delineated. FOIA There is no such thing as attention. Sheliga, B. M., Riggio, L., & Rizzolatti, G. (1995). It has its own methodology, notably repertory grid technique and the self-characterization, and . government site. Spatial attention and eye movements. Journal of Experimental Psychology: Human Perception and Performance, 18, 891905. (1995). Although this might seem an absurd example (presumably no one would use a tape measure to measure intelligence), it demonstrates that validity is not a property of the measurement instrument but of the inference being made. doi: 10.1016/j.pmip.2021.100078. Modern validity theory posits that all validation is singly focused on providing evidence to support the interpretation or the inference. The problem of this analytic approach is that it underestimates and overlooks commonalities between subfunctions and, in a wider perspective, commonalities with other concepts. Value-driven attentional capture. 3). Proceedings of the National Academy of Sciences of the United States of America, 108, E1433-1440. Khan, A. This means that selectivity is an emerging property arising from a myriad underlying processes, and the simple fact that humans (and other species showing selective attention) evolved the way they did, with selective attention being one of many byproducts, next to selective intention and selective decision making. Here, we have primarily emphasized selection mechanisms in the superior colliculus and parietal cortex, but similar arguments can be made for other selection mechanisms in other brain regions. Cambridge, MA: MIT Press. PubMed Central A similar tendency can be seen with respect to selective attention, where Awh, Belopolsky, and Theeuwes (2012) have tried to integrate findings that are no longer consistent with the historical distinction between endogenous attention, which represents the prioritized processing of stimuli to which the agent wants to attend, and exogenous attention, which represents the prioritized processing of stimuli that are unrelated to the present action and goals. Visual Cognition, 5, 81107. However, this influence implies that selection history affects how goals impact (endogenous) attention. Although this approach may account for many of the available findings, we are not convinced that it really solves the problem, but rather provides a patch that holds concepts together and, in the end, prevents or misdirects the search for suitable solutions. Gandhi, N. J., & Katnani, H. A. Constructs summarize behavioral domains. In early mammals (300 Mya), this system was probably quite limited and consisted simply of medial circuits concerned with locomotion and lateral circuits concerned with head and mouth movements (Kaas, 2017). Hommel, B., Chapman, C.S., Cisek, P. et al. https://doi.org/10.1073/pnas.1104047108, Article 2012 Mar 30;196(1):38-44. doi: 10.1016/j.psychres.2011.08.021. Other studies (Bekkering & Neggers, 2002; Moher, Anderson, & Song, 2015; Tipper, Meegan, & Howard, 2002; Weir et al., 2003; Welsh & Pratt, 2008; Welsh & Zbinden, 2009; see also Gallivan, Barton, Chapman, Wolpert, & Flanagan, 2015; Glazebrook, Welsh, & Tremblay, 2016; Yoxon, Constable, & Welsh, 2019 [this issue]) show that the processing of specific object features can be prioritized depending on the relative (i.e., task/action-specific) salience of those features for the to-be-performed action. (2018). Working memory is generally used synonymously with short term memory, but this depends on how the two forms of memory are defined. Note that many branch points and lineages are omitted for clarity. Cognitive psychology: A students handbook (4th Ed.). This approach looks at consciousness by learning more about the physical processes that underlie our conscious experiences. Katz, L. N., Yates, J. L., Pillow, J. W., & Huk, A. C. (2016). Selective modulation of early visual cortical activity by movement intention. and transmitted securely. 155-189). Glazebrook, C.M., Welsh, T.N., & Tremblay, L. (2016). In particular, the idea is that goals (the factor responsible for endogenous attention), salience (the factor responsible for exogenous attention), and selection history (a factor that does not seem to fit the previous dichotomy and is associated with previous selections and rewards generated by the selections) all contribute to selectivity by sending their output to an integrative priority map. These two activities circumscribe the universe of relevant content and constrain the set of inferences that one hopes to support. Journal of Neurophysiology, 104, 1538-1548. Unlike the standard models of short term/working memory, unitary theories do not assume a direct connection between activation level and memory success. Often, this type of evidence is referred to as convergent and discriminant validity, respectively. (2004). 739752) Cambridge, MA: MIT Press. Further, everything an individual does throughout their life (distant and recent past) creates, reinforces, and shapes selection: Turning to the left makes us ignore stimuli on the right, picking one apple makes us overlook the others, saying one word prevents us from uttering any other. Neuron, 81, 1401-1416. The neural-systems framework can broaden empirical horizons in comparative psychology. Atten Percept Psychophys 81, 22882303 (2019). We make the case for adopting a synthetic approach to studying cognitive phenomena wherein the focus is on the subset of processes and mechanisms that have been attributed to and investigated under the umbrella of attention, rather than on attention as one overarching concept. n. 1. a complex idea or concept formed from a synthesis of simpler ideas. Having the quality of oneness. Vision Research, 48, 85361. Second, the term attention is often used to capture both the problem and the solution of cognitive processing; i.e., to describe both the phenomenon one aims to explain and the mechanism proposed to provide the explanation. Trends in Cognitive Science, 18, 457-64. https://doi.org/10.1016/j.tics.2014.05.008. But what is the solution to this and the many other conceptual problems we are encountering in thinking about human attention (e.g., controlled vs. automatic processing; facilitation vs. inhibition, etc.)? Trends in Cognitive Sciences, xx, 113. For instance, the term attention is used to refer to the consequences of both voluntary and involuntary factors in favoring the representation of one event having a stronger impact on decision making and action than representations of other events (e.g., Yantis, 1998). Epub 2014 Feb 26. The sketchpad can be further broken down into a visual subsystem (dealing with, for instance, shape, colour, and texture), and a spatial subsystem (dealing with location). Treatment durations are similarly broad. 2018 Nov;93(4):1795-1812. doi: 10.1111/brv.12421. Your consciousness may then shift to the memory of a conversation you had earlier with a co-worker. A parametric fMRI study of overt and covert shifts of visuospatial attention. (Eds. It can, for example, maintain a seven-digit telephone number for as long as one repeats the number to oneself again and again. The control of gaze involves the lateral intraparietal area (Snyder, Batista, & Andersen, 2000), which represents space in a retinotopic frame (Colby & Duhamel, 1996; Snyder, Grieve, Brotchie, & Andersen, 1998), and is interconnected with frontal regions controlling gaze, such as the frontal eye fields and the superior colliculus (Par & Wurtz, 2001) taking advantage of the tectal orientation/approach system that has been steering animals since the Cambrian epoch. In the present paper, we start by discussing and outlining the central problem with the way attention has been conceptualized and studied thus far. Essentially, your consciousness is your awareness of yourself and the world around you. Nakamura, H., Kuroda, T., Wakita, M., Kusunoki, M., Kato, A., Mikami, A., Sakata, H., & Itoh, K. (2001). Probabilistic decision making by slow reverberation in cortical circuits. We thus conclude that selectivity emerged through evolution as a design feature to enable efficient goal-directed action. Quarterly Journal of Experimental Psychology Section A, 57, 1031-1057. Psychological Science, 13, 370-374. - 208.109.32.93. In a sense, all validity inferences are part of construct validity. ", "The episodic buffer: a new component of working memory? (2004). The second common misconception is that there are different types of validity. Attention and effort. MeSH Another reason why just adding selection history as an additional factor raises more questions than answers is that the concept itself is unclear, particularly in its overlap with other related factors beyond exogenous and endogenous control. Scientific Reports, 8, 8611. Conscious: What's the Difference? The latter includes parts of the lateral prefrontal cortex, orbitofrontal cortex, and all of the limbic cortex and the temporal lobe. More specifically, we argue that the concept of attention is one of the most misleading and misused terms in the cognitive sciences. The history of distinguishing between endogenous and exogenous attention is very similar to the distinction between attention and intention. Intention-related activity in the posterior parietal cortex: a review. Spatial representations for action in parietal cortex. Rizzolatti, G., & Luppino, G. (2001). Grounding attention in action control: The intentional control of selection. For those that do not, here are some explanations of the technical terms use. The problem here is similar to the one Awh et al. It is uncontroversial that previously rewarded stimuli receive preferential processing (Anderson, Laurent, & Yantis, 2011; Anderson & Yantis, 2012), suggesting that reward history is important in determining salience. Visual Cognition, 9, 591-614. Current Biology, 25, 2040-2046. https://doi.org/10.1016/j.cub.2015.06.029. The present paper reaffirms and expands this position by placing particular and new emphasis on the interconnected and integrative nature of the human sensorimotor information processing systems. Buckner, R.L., & Schacter, D.L. Although the goal of comparative psychology lies in generating principles of generality concerning behavior rather than in direct extrapolation to humans, results can provide worthwhile hypotheses regarding the evolution of human behavior. Philadelphia: Psychology Press. Hence, we argue that, in contrast to Jamess (1890) assertion, no one knows, or can ever know, exactly what attention is. Very nice, very good 1965 Mustang Coupe. Control of visual attention. 2017. doi:10.1002/9781119132363.ch16. How emotions are made: The secret life of the brain. Schizophr Bull. While the cues are present, the nerves that form the constellation are active and the memory is being worked on in short term memory. For example, loss aversion, made famous by the work of Kahneman and Tversky (1979), shows that people treat potential losses as being more aversive than equivalent gains are rewarding. While more work needs to be done to synthesize these neural and behavioral observations into a coherent framework, it seems clear (to us) that the conceptual distinction between attention and intention is not sufficient to account for the variety of findings discussed here. 2021 Jul;27-28:10.1016/j.pmip.2021.100078. The Well-Being Index scale (WHO-5) is a generic, self-report scale that contains five Likert-type items to evaluate psychological well-being. Science, 334, 10911097. (2008). Today, consciousness is generally defined as an awareness of yourself and the world. The present study examined the latent factor structure of the Brief Assessment of Cognition in Schizophrenia (BACS) neuropsychological battery. Talking to your doctor right away can ensure that you get immediate treatment before problems get worse. Schizophr Res. Post the Definition of unitary theory to Facebook, Share the Definition of unitary theory on Twitter, More than 250,000 words that aren't in our free dictionary, Expanded definitions, etymologies, and usage notes. Yoxon, E., Constable, M.D., & Welsh, T.N. In the present paper, we stake the position that the term attention should be abandoned and the nature of the research in this area be re-conceptualized to focus on the subsets of processes and mechanisms that lead to task-specific performance. When used appropriately, the application of the tape measure will generate observed measurements (e.g., inches, millimeters, feet) that correspond closely to actual differences in height. Thick lines indicate the presence of relevant fossil data (paleobiodb.org). (2012), one reason is that selection history overlaps considerably with goal-induced endogenous selectivity and salience-induced exogenous selectivity. Awh, E., Belopolsky, A. V., & Theeuwes, J. Both rates are implausible, as a constant rate of decay neglects all external factors that may contribute to a faster rate of decay (e.g. For example, inferences about individual differences in peoples height based on the observed scores generated from the use of a (normal) tape measure or ruler are highly valid. Englewood Cliffs, NJ: Prentice-Hall. When a memory is formed, cues associated with the formed memory form a constellation of nerve networks in which the memory is stored. Refining the time course of facilitation and inhibition in attention and action. Unitary theories of memory are hypotheses that attempt to unify mechanisms of short-term and long-term memory. And so, this brief foray into the long journey of primate evolution has brought us back to selective attention and to the posterior parietal cortex, but with a different perspective on both. Motor functions of the superior colliculus. The feature model was first described by Nairne (1990)[2] The primary feature of this model is the use of cues for both short term memory and long term memory. (1982). Google Scholar, Anderson, B. Top-down versus bottom-up atten-tional control: A failed theoretical dichotomy. Consciousness is your individual awareness of your unique thoughts, memories, feelings, sensations, and environments. It is common to hear people refer to the validity of the test, which might give the impression that validity is a property of the measurement device.
