Memory predictions are influenced by perceptual information: evidence for metacognitive illusions

Although perceptual information is utilized to judge size or depth, little work has investigated whether such information is used to make memory predictions. The present study examined how the font size of to-be-remembered words influences predicted memory performance. Participants studied words for a free-recall test that varied in font size and made judgments of learning (JOLs) for each item. JOLs were influenced by font size, as larger font sizes were given higher JOLs, whereas little relationship was evident between font size and recall. The effect was modified when other, more valid, sources of information (e.g., associative strength) were available when JOLs were made and persisted despite experience with multiple study-test sessions, use of a forgetting scale to assess predictions, and explicit warning of participants that font size has little effect on memory performance. When ease of reading was manipulated, such that large font size words were made less fluent, the effect was eliminated. Thus, highly accessible perceptual cues can strongly influence JOLs, likely via encoding fluency, and this effect can lead to metacognitive illusions     

Frequency and nature of rumination in chronic depression: a preliminary study

This study explores the phenomenological experience of rumination in a sample of 22 chronically depressed people and looks at the extent to which it is consistent with theoretical ideas. The findings indicate that, on average, depressed people ruminate about at least two different topics, and that there is wide variability in how long each episode lasts. Rumination is a complex process frequently involving imagery as well as verbal thoughts and is almost invariably associated with multiple emotions. Although there was some evidence for stop rules being involved, most individuals attributed ending a period of rumination to distraction, whether external or internally generated.     

Do government brochures affect physical activity cognition? A pilot study of Canada's physical activity guide to healthy active living

Health Canada has published national physical activity (PA) guidelines, which are included in their 26-page Physical Activity Guide to Healthy Active Living (CPAG). To date, the use of CPAG as a motivational instrument for PA promotion has not been evaluated. The purpose of this study was to determine whether reading CPAG 1) increased motivational antecedents to engage in regular PA, and 2) increased regular PA intention and behaviour over 1 month. Participants included 130 randomly sampled Canadian adults (18 years or older) who were randomly mailed pack ages consisting of either 1) a questionnaire and a copy of CPAG, or 2) a questionnaire. Questionnaire items pertained to participants' sociodemographics, previous PA behaviours (Godin Leisure-Time Questionnaire) and PA motivation (theory of planned behaviour). Participants were then sent a follow-up questionnaire pertaining to their PA behaviours throughout the previous month. Results revealed significant interactions between the guide condition and previous activity status on instrumental behavioural beliefs about strength activities and subjective norms about endurance activities (p < 0.05), but all other factors were not significantly different. It was concluded that among previously inactive people, receiving this guide may change some informational/motivational constructs, but key motivational antecedents (affective attitude, perceived behavioural control) and outcomes (intention, behaviour) seem unaffected.     

Students’ Perceptions of School Climate During the Middle School Years: Associations with Trajectories of Psychological and Behavioral Adjustment

A cross-domain latent growth curve model was used to examine the trajectories of change in student perceptions of four critical dimensions of school climate (i.e., teacher support, peer support, student autonomy in the classroom, and clarity and consistency in school rules and regulations) among 1,451 early adolescents from the beginning of sixth through the end of eighth grade; and the effects of such trajectories on the rate of change in psychological and behavioral adjustment. Findings indicated that all of the dimensions of perceived school climate declined over the 3 years of middle school. Furthermore, declines in each of the dimensions of perceived school climate were associated with declines over time in psychological and behavioral adjustment. Moreover, the direction of effects between each dimension of perceived school climate and psychological or behavioral adjustment were often unidirectional rather than bi-directional, underscoring the role of perceived school climate in the psychological and behavioral health of early adolescents. Gender and socioeconomic class differences in these patterns are noted.     

The role of the psychologist in crisis/hostage negotiations

Over the past three decades, there has been a noted increase in hostage and barricade incidents involving perpetrators with a variety of emotional, economic, and political motives. A hostage incident may be defined as an incident in which (a) perpetrator(s) hold(s) one or more persons against their will in a location known to police. A barricade incident, on the other hand, is an incident without hostages in which a perpetrator is barricaded, also in a location known to police and refusing to surrender. Approximately 25 years ago, a theory of crisis/hostage negotiations was developed which has been continuously refined in field applications. This article will define the goal of crisis/hostage negotiation, review the history of hostage taking from biblical times to the present, review the utilization of psychologists and other mental health consultants by police crisis/hostage negotiation teams, and discuss the four roles and related functions of psychologists on crisis/hostage negotiation teams. © 1998 John Wiley & Sons, Ltd.     

Normative Social Role Concepts in Early Childhood

The current studies (N = 255, children ages 4–5 and adults) explore patterns of age‐related continuity and change in conceptual representations of social role categories (e.g., “scientist”). In Study 1, young children's judgments of category membership were shaped by both category labels and category‐normative traits, and the two were dissociable, indicating that even young children's conceptual representations for some social categories have a “dual character.” In Study 2, when labels and traits were contrasted, adults and children based their category‐based induction decisions on category‐normative traits rather than labels. Study 3 confirmed that children reason based on category‐normative traits because they view them as an obligatory part of category membership. In contrast, adults in this study viewed the category‐normative traits as informative on their own (not only as a cue to obligations). Implications for continuity and change in representations of social role categories will be discussed.     

‘The witness who saw, /he left little doubt’: a comparative consideration of expert testimony in mental disability law cases in common and civil law systems

The question of how courts assess expert evidence—especially when mental disability is an issue—raises the corollary question of whether courts adequately evaluate the content of the expert testimony or whether judicial decision making may be influenced by teleology (‘cherry picking’ evidence), pretextuality (accepting experts who distort evidence to achieve socially desirable aims), and/or sanism (allowing prejudicial and stereotyped evidence). Such threats occur despite professional standards in forensic psychology and other mental health disciplines that require ethical expert testimony. The result is expert testimony that, in many instances, is at best incompetent and at worst biased. The paper details threats to competent expert testimony in a comparative law context—in both the common law (involuntary civil commitment laws and risk assessment criminal laws) and, more briefly, civil law. We conclude that teleology, pretextuality, and sanism have an impact upon judicial decision making in both the common law and civil law. Finally, we speculate as to whether the new United Nations Convention on the Rights of Persons with Disabilities is likely to have any impact on practices in this area.

Infants' use of social partnerships to predict behavior

The experiences of social partners are important motivators of social action. Can infants use such experiences to make predictions about how social agents will behave? Sixteen‐month‐old infants were introduced to two social pairs. Initial events established within‐pair cooperation as well as between‐pair conflict involving an individual from each pair. Following these events, infants looked longer when between‐pair members who had never previously interacted now cooperated – instead of conflicted – with each other. Thus, infants tracked the third‐person allegiances and inferred that the conflict would generalize across social partnerships. These findings demonstrate a critical feature of early social cognition and promote needed, further research on the role of social allegiances in social cognition across development.
