> Abstract:
> Interest in convexity has a long history in vision science. For smooth
> contours in an image, it is possible to code regions of positive
> (convex) and negative (concave) curvature, and this provides useful
> information about solid shape. We review a large body of evidence on the
> role of this information in perception of shape and in attention. This
> includes evidence from behavioral, neurophysiological, imaging, and
> developmental studies. A review is necessary to analyze the evidence on
> how convexity affects (1) separation between figure and ground, (2) part
> structure, and (3) attention allocation. Despite some broad agreement on
> the importance of convexity in these areas, there is a lack of consensus
> on the interpretation of specific claims-for example, on the
> contribution of convexity to metric depth and on the automatic directing
> of attention to convexities or to concavities. The focus is on convexity
> and concavity along a 2-D contour, not convexity and concavity in 3-D,
> but the important link between the two is discussed. We conclude that
> there is good evidence for the role of convexity information in
> figure-ground organization and in parsing, but other, more specific
> claims are not (yet) well supported.

> Abstract:
> The spatial knowledge used for human navigation has traditionally been
> separated into three categories: landmark, route, and survey knowledge.
> While behavioral research has retained this framework, it has become
> increasingly clear from recent neuroimaging studies that such a
> classification system is not adequate for understanding the brain. This
> review proposes a new framework, with a taxonomy based on the cognitive
> processes and subprocesses involved in spatial navigation. The neural
> correlates of spatial memory can inform our understanding of the
> cognitive processes involved in human navigation, and conversely, the
> specific task demands of an experiment can inform the interpretation of
> neuroimaging results. This review examines the neural correlates of each
> cognitive process separately, to provide a closer inspection of each
> component of spatial navigation. While landmark, route, and survey
> knowledge are still important components of human navigation, the neural
> correlates are not neatly ascribed to these three categories. The

> Abstract:
> Working memory (WM) and attention have been studied as separate
> cognitive constructs, although it has long been acknowledged that
> attention plays an important role in controlling the activation,
> maintenance, and manipulation of representations in WM. WM has,
> conversely, been thought of as a means of maintaining representations to
> voluntarily guide perceptual selective attention. It has more recently
> been observed, however, that the contents of WM can capture visual
> attention, even when such internally maintained representations are
> irrelevant, and often disruptive, to the immediate external task. Thus,
> the precise relationship between WM and attention remains unclear, but
> it appears that they may bidirectionally impact one another, whether or
> not internal representations are consistent with the external perceptual
> goals. This reciprocal relationship seems, further, to be constrained by
> limited cognitive resources to handle demands in either maintenance or
> selection. We propose here that the close relationship between WM and
> attention may be best described as a give-and-take interdependence
> between attention directed toward either actively maintained internal
> representations (traditionally considered WM) or external perceptual
> stimuli (traditionally considered selective attention), underpinned by
> their shared reliance on a common cognitive resource. Put simply, we
> argue that WM and attention should no longer be considered as separate
> systems or concepts, but as competing and influencing one another
> because they rely on the same limited resource. This framework can offer
> an explanation for the capture of visual attention by irrelevant WM
> contents, as well as a straightforward account of the underspecified
> relationship between WM and attention.

> Abstract:
> Criminal suspects with distinctive facial features, such as tattoos or
> bruising, may stand out in a police lineup. To prevent suspects from
> being unfairly identified on the basis of their distinctive feature, the
> police often manipulate lineup images to ensure that all of the members
> appear similar. Recent research shows that replicating a distinctive
> feature across lineup members enhances eyewitness identification
> performance, relative to removing that feature on the target. In line
> with this finding, the present study demonstrated that with young adults
> (n = 60; mean age = 20), replication resulted in more target
> identifications than did removal in target-present lineups and that
> replication did not impair performance, relative to removal, in
> target-absent lineups. Older adults (n = 90; mean age = 74) performed
> significantly worse than young adults, identifying fewer targets and
> more foils; moreover, older adults showed a minimal benefit from
> replication over removal. This pattern is consistent with the
> associative deficit hypothesis of aging, such that older adults form
> weaker links between faces and their distinctive features. Although
> replication did not produce much benefit over removal for older adults,
> it was not detrimental to their performance. Therefore, the results
> suggest that replication may not be as beneficial to older adults as it

> Abstract:
> After attention has been involuntarily captured by a distractor, how is

> The present study investigated this issue with event-related potentials
> (ERPs), focusing on the N2pc component (a neural measure of attentional
> deployment) and the Pd component (a neural measure of attentional
> suppression). Observers identified a color-defined target in a search
> array, which was preceded by a task-irrelevant cue array. When the cue
> array contained an item that matched the target color, this item
> captured attention (as measured both behaviorally and with the N2pc
> component). This capture of attention was followed by active suppression
> (indexed by the Pd component), and this was then followed by a
> reorienting of attention toward the target in the search array (indexed
> by the N2pc component). These findings indicate that the involuntary
> capture of attention by a distractor is followed by an active

> Abstract:
> The Iowa gambling task (IGT) has been used in numerous studies, often to
> examine decision-making performance in different clinical populations.
> Reinforcement learning (RL) models such as the expectancy valence (EV)
> model have often been used to characterize choice behavior in this work,
> and accordingly, parameter differences from these models have been used
> to examine differences in decision-making processes between different
> populations. These RL models assume a strategy whereby participants
> incrementally update the expected rewards for each option and
> probabilistically select options with higher expected rewards. Here we
> show that a formal model that assumes a win-stay/lose-shift (WSLS)
> strategy-which is sensitive only to the outcome of the previous
> choice-provides the best fit to IGT data from about half of our sample
> of healthy young adults, and that a prospect valence learning (PVL)
> model that utilizes a decay reinforcement learning rule provides the
> best fit to the other half of the data. Further analyses suggested that
> the better fits of the WSLS model to many participants' data were not
> due to an enhanced ability of the WSLS model to mimic the RL strategy
> assumed by the PVL and EV models. These results suggest that WSLS is a
> common strategy in the IGT and that both heuristic-based and RL-based
> models should be used to inform decision-making behavior in the IGT and
> similar choice tasks.

> Abstract:
> In memory-based decision making, people often rely on simple heuristics
> such as take-the-best (TTB; Gigerenzer & Goldstein, Psychological
> Review, 103, 650-669, 1996), which processes information about the
> alternatives sequentially and stops processing as soon as a decision can
> be made. In this article, we examine the memory processes associated
> with TTB-in particular, to what degree the selective memory retrieval of
> relevant information required by TTB is accompanied by automatic
> activation of associated but irrelevant information. To address this
> question, we studied the fan effect (Anderson, Cognitive Psychology, 6,
> 451-474, 1974), which is assumed to arise from automatic spread of
> activation, in inferences from memory. Participants were instructed to
> use TTB when making decisions about objects on the basis of previously
> memorized attribute information. Both the number of attributes required
> by TTB and the number of attributes associated with an object (i.e., fan
> level) were manipulated. As it turned out, response times and the
> correct execution of TTB were a function not only of the number of
> required attributes, but also of the number of associated attributes.
> This suggests that information that TTB "ignores" is nevertheless
> activated in memory.

> Abstract:
> Discovering how people judge their memories has been a major issue for
> metacognitive research for over 4 decades; many factors have been
> discovered that affect people's judgments, but exactly how those effects
> are mediated is poorly understood. For instance, the effect of word pair
> relatedness on judgments of learning (JOLs) has been repeatedly
> demonstrated, yet the underlying basis of this substantial effect is
> currently unknown. Thus, in three experiments, we assessed the
> contribution of beliefs and processing fluency. In Experiment 1,
> participants studied related and unrelated word pairs and made either
> prestudy JOLs or immediate JOLs. Participants gave higher estimates for
> related than for unrelated pairs, suggesting that participants' beliefs
> at least partially drive the relatedness effect on JOLs. Next, we
> evaluated the contribution of processing fluency to the relatedness
> effect either (1) by disrupting fluency by presenting half the pairs in
> an aLtErNaTiNg format (Experiment 2) or (2) by measuring how fluently
> participants processed pairs at study and statistically estimating the
> degree to which conceptual fluency mediated the effects of relatedness
> on JOLs (Experiment 3). Results from both experiments indicated that
> fluency contributes minimally to the relatedness effect. Taken together,
> these results indicate that people's beliefs about how relatedness
> influences memory are responsible for mediating the relationship between
> relatedness and JOLs. In general, empirically establishing what mediates
> the effects of other factors on people's judgments remains a major
> agenda for advancing theory of metacognitive monitoring.

> Abstract:
> Guilt by association and honor by association are two types of judgments

> Here, we provide experimental evidence of guilt by association and honor

> Abstract:
> A great deal of research into the experiential nature of language has

> "The old lady [knows/thinks] that the picnic basket is open." Following
> a delay of 250 or 1,500 ms, they responded to pictures that varied in
> the physical form of the target object (matching vs. mismatching).
> Results revealed an expected facilitation effect for matching images,
> but more important, they also showed interference effects (longer
> reaction times) at the shorter interstimulus interval (ISI; 250 ms)
> following the uncertain verb thinks, as compared with the certain verb
> knows. At the longer ISI, this effect was no longer present. This
> suggests that at the short ISI, uncertain conditions required extra time
> to construct and map a simulation of events onto the available image.
> Results are discussed in terms of the mechanisms involved in
> representing possible events and with reference to related literature on
> perspective taking.
