Mental representations of familiar faces

The Bruce and Young (1986) framework makes a number of important distinctions between the types of representation needed to recognize a familiar face. Here, we return to these, focussing particularly on face recognition units. We argue that such representations need to incorporate idiosyncratic within-person variability, asking questions such as 'What counts as a picture of Harrison Ford?'. We describe a mechanism for achieving this, and discuss the relation between image variability and episodic face memories, in the context of behavioural and neurophysiological data.     

On the adaptive flexibility of evaluative priming

If priming effects serve an adaptive function, they have to be both robust and flexible. In four experiments, we demonstrated regular evaluative-priming effects for relatively long stimulus-onset asynchronies, which can, however, be eliminated or reversed strategically. When participants responded to both primes and targets, rather than only to targets, the standard congruity effect disappeared. In Experiments 1a–1c, this result was regularly obtained, independently of the prime response (valence or gender classification) and the response mode (pronunciation or keystroke). In Experiment 2, we showed that once the default congruity effect was eliminated, strategic-priming effects reflected the statistical contingency between prime valence and target valence. Positive contingencies produced congruity, whereas negative contingencies produced equally strong incongruity effects. Altogether, these findings are consistent with an adaptive-cognitive perspective, which highlights the role of flexible strategic processes in working memory as opposed to fixed structures in semantic long-term memory or in the sensorimotor system.     

Attachment, parenting, and separation--individuation in adolescence: a comparison of hospitalized adolescents, institutionalized delinquents, and controls

The authors compared parent-related perceptions by hospitalized adolescents (i.e., who were admitted to a specialized psychiatric unit; n = 50) and delinquent adolescents (i.e., who were placed at a juvenile treatment institution; n = 51) with adolescents from the general population (n = 51). All adolescents completed a broad set of measures of attachment, perceived parenting, and separation-individuation. Contrary to initial expectations, hospitalized adolescents scored higher than controls on indices of excessive autonomy. Ambivalence regarding issues of interpersonal closeness and distance was found among delinquent adolescents. In addition, hospitalized and delinquent adolescents were found to be struggling, each in their specific way, with attachment-related experiences of trauma. Finally, delinquent adolescents also showed a stage-appropriate form of potentially adaptive narcissism. These findings add to the growing consensus in the literature that associations between adolescent psychopathology and parent-related perceptions are typically complex and somewhat counterintuitive.     

On the relations between distinct aspects of psychological distance: An ecological basis of construal-level theory

Construal-level theory's basic assumption of a positive relationship between psychological distance and abstractness of mental representations presupposes a unitary distance construct. Although prior research testifies to convergent influences of temporal, spatial, social and reality (probability) distance, there is no direct evidence for the integration function of all four major distance aspects assessed within the same study with reference to the same target objects. Does high (low) distance in any aspect imply high (low) distance in all other aspects, or are discounting effects (e.g., high temporal distance rendering high personal distance obsolete) sometimes apparent in negative correlations? In pursuing this question, we obtained strong and regular positive correlations between all four distance aspects, across judges and judgment targets, regardless of whether freely construed future episodes or really experienced past episodes were judged. Existing ecological correlations seem to account for the positive relationship between time, space, probability and temporal distance.     

Telehealth for underserved families: An evidence-based parenting program

Families with a child diagnosed with attention-deficit hyperactivity disorder completed an 8-session parenting program, the Group Triple P Positive Parenting Program, provided by videoconferencing technology. Families reported improved child behavior (effect size of d = -1.23) and decreased parent distress (d = -0.34). Parent training implemented with videoconferencing technology can be an effective way of delivering evidence-based services to families with specialized needs.

Mood effects on dominated choices: Positive mood induces departures from logical rules

In two studies, we investigated the role of mood states in dominated behavioral choices. Past research has shown that mood effects on judgment and decision‐making can be pervasive. Yet, the role of mood in dominated choices has so far been neglected. The present research represents a first empirical examination of mood effects on dominated choices. We measured (Study 1) or manipulated (Study 2) mood states in participants who made a series of choices in a gambling game. In this choice task without trade‐offs, participants were provided with information about the outcomes and probabilities associated with each choice option. The strategy to maximize the expected mean outcome implied the application of a straightforward and logical rule: Always choose the dominant option with the highest expected value. It has been argued in the literature that mood should have little or no impact when preferences are clear or strong. Still, we expected that mood states would affect even these dominated choices, building on previous work that showed that positive mood states enhance flexibility, creativity, and explorative behavior. The results showed that decisions made in a happier mood were less often in accordance with the logical rule than decisions made in a sadder mood. To conclude, happier mood states are associated to a lesser extent with decisions in accordance with a rule‐based strategy that maximizes expected mean outcomes in dominated choices.

A connectionist implementation of the theory of planned behavior: association of beliefs with exercise intention.

The theory of planned behavior suggests attitudes are a product of salient beliefs. This study examined whether aggregating salient beliefs was plausible within a more biologically centered information-processing environment. A neural network was used to examine associations among beliefs relating to exercise intention. Data on intentions and behavioral, normative, and control beliefs from 114 respondents were used to train (by error backpropagation) a neural network to associate beliefs with intention. The R-sup-2 between the network's estimated and self-reported intention was.66. The network's representation comprised 6 belief profiles associated with high, moderate, or low behavioral intention. The neural network accommodated complex relationships among beliefs and belief-intention associations and indicated how high-level constructs such as attitudes may be viewed as the best fit (compromise state) between aroused beliefs.     

Dimensions of On-the-Job Learning Styles

The aim of this study is to identify dimensions of on‐the‐job learning styles that can create an awareness among employees and offer them opportunities for the improvement of their on‐the‐job learning. In order to be able to select relevant dimensions, we propose four criteria: dimensions should: (a) concern activities and behaviour; (b) be changeable by learners; (c) be applicable to the workplace context; and (d) be uni‐dimensional. After reviewing the literature in light of these criteria, we conclude that employees need to be aware of four core dimensions of on‐the‐job learning styles: (a) whether they are reproductive or developmental learners; (b) whether they tend to learn alone, from others, or with others; (c) whether they are holistic or analytical learners; and (d) how they engage in reflection (e.g. the depth of reflection). Le but de cette étude est d’identifier les dimensions composant des styles d’apprentissage sur le tas et plus particulièrement la création d’une conscience parmi les salariés et l’opportunité d’accroître les possibilités d’apprentissage sur le tas. Afin de sélectionner des dimensions appropriées, nous proposons 4 critères: les dimensions doivent a) concerner des activités et le comportement, b) être variables selon les apprenants, c) être applicable dans un contexte de travail et d) être uni‐dimensionnel. Une revue de la littérature à la lumière de ces critères montre que les salariés ont besoin d’être conscients de 4 dimensions fondamentales des styles d’apprentissage sur le tas: a) Sont‐ils des apprenants “passifs” ou “actifs” ? b) Tendent‐ils à apprendre seul, avec d’autres ou d’autres personnes ? c) Sont‐ils des apprenants holistiques ou analytiques ? et d) Quelle est la façon dont ils s’engagent dans une réflexion (e.g. la profondeur de la réflexion)?     

Adaptation in conflict: are conflict-triggered control adjustments protected in the presence of motivational distractors?

Solving a conflict between two response options in an interference task has been found to increase control in a subsequent conflict situation. The present research examined whether such conflict adaptation persists in the presence of distractors that have motivational relevance and are therefore competing for attentional resources (i.e. they signal opportunities for monetary gains or losses contingent on overall task performance). In an adjusted flanker task, motivational (versus neutral versus no) distractors were presented together with the current trial while the previous trial never included any distractor. Accumulated evidence across three studies showed that motivational distractors reduced the conflict adaptation effect. This was found irrespective of the location at which the distractor occurred (Study 1), and independent of its valence (i.e. reward or loss, Study 2). Study 3 and a merged data analysis ruled out low-level alternative explanations. In line with a dual competition account (Pessoa, L. (2009). How do emotion and motivation direct executive control? Trends in Cognitive Sciences, 13(4), 160–166. doi:10.1016/j.tics.2009.01.006), our results show that conflict adaptation is not fully protected in the presence of motivational distractors. We discuss whether this should be interpreted as a limitation, or as reflecting the flexibility of the control system in dealing with motivationally relevant information.
