The perceptual span during foveally-demanding visual target localization

Foveally-induced processing load deteriorates target localization performance in vision-guided tasks. Here, participants searched for a target embedded among coded distractors. High processing load was effected by instructing some participants to use the coded distractors to guide their search for the target. Other participants (in the low processing load condition) were not apprised of the code. The experiment examined whether increased processing load alters the span of effective processing (i.e. perceptual span) by (a) reducing its size, (b) altering its shape, or (c) reducing its size and altering its shape. The results demonstrated a reduction in the size of the perceptual span, with no significant change to its shape. It is argued that when distractors are processed beyond simply rejecting them as non targets, the perceptual span shrinks with increasing processing load. The findings are discussed in contrast to a general interference theory that predicts a change in vision-guided performance without a shrinking of the perceptual span.     

Introduction: babies in the consulting room: what happens when analyst, mother, and infant meet?

Analytic work with a pregnant woman may foster the psychological gestation of the self-as-mother. For the mother--as for the infant--the developmental process continues well beyond delivery. It should not surprise us, then, that many mothers continue to bring their babies to sessions after birth. Analytic work in this context can affect a patient's sense of herself, and perhaps her competence, as a mother. Yet the presence of babies in the consulting room is an underacknowledged feature of contemporary practice. For this section of JAPA, we have collected three papers that explore some of the unique challenges and opportunities that arise when a patient brings her baby to treatment. Earlier versions of each paper were first presented at a panel, "Babies in the Consulting Room," at the June 2011 meeting of the American Psychoanalytic Association in San Francisco.     

The compensation and capitalization models: A test of two approaches to individualizing the treatment of depression

Despite long-standing calls for the individualization of treatments for depression, modest progress has been made in this effort. The primary objective of this study was to test two competing approaches to personalizing cognitive-behavioral treatment of depression (viz., capitalization and compensation). Thirty-four adults meeting criteria for Major Depressive Disorder (59% female, 85% Caucasian) were randomized to 16-weeks of cognitive-behavioral treatment in which strategies used were selected based on either the capitalization approach (treatment matched to relative strengths) or the compensation approach (treatment matched to relative deficits). Outcome was assessed with a composite measure of both self-report (i.e., Beck Depression Inventory) and observer-rated (i.e., Hamilton Rating Scale for Depression) depressive symptoms. Hierarchical linear modeling revealed a significant treatment approach by time interaction indicating a faster rate of symptom change for the capitalization approach compared to the compensation approach (d = .69, p = .03). Personalizing treatment to patients' relative strengths led to better outcome than treatment personalized to patients' relative deficits. If replicated, these findings would suggest a significant change in thinking about how therapists might best adapt cognitive-behavioral interventions for depression for particular patients.     

Taking stress response out of the box: stability, discontinuity, and temperament effects on HPA and SNS across social stressors in mother-infant dyads

This study investigated continuity and stability of hypothalamic-pituitary-adrenal (HPA) and sympathetic nervous system (SNS) response measures in mother-infant dyads across 2 different types of social stress sessions. Synchrony of response trajectories across systems (SNS-HPA coordination) and partners (mother-infant attunement) was addressed, as were associations with infant temperament. Primiparous mothers and their 18-month-old infants (n = 86 dyads) completed an attachment stressor--Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978)--at Session 1 and challenge stressors--cleanup task and emotion task battery--at Session 2. Mother and infant saliva samples collected to index pre-stress, stress, and post-stress response during each session were assayed for cortisol (HPA marker) and salivary alpha-amylase (sAA; SNS marker). Multilevel modeling of cortisol/sAA trajectories across sessions revealed rank-order stability in mother/infant stress measures but discontinuity in absolute levels; cortisol trajectories were higher during attachment stress, and sAA trajectories were higher during challenge stress. Varying degrees of mother-infant attunement were found across sessions/systems. Infant surgency predicted higher stress measures, and negative affect and effortful control predicted lower stress measures, though associations depended on session/system. Findings are discussed in terms of advancing a multisystemic, contextual definition of developing stress responsiveness.     

A factor analytic investigation of the BASC-2 Behavioral and Emotional Screening System Parent Form: psychometric properties, practical implications, and future directions

The Behavior Assessment System for Children, Second Edition (BASC-2) Behavioral and Emotional Screening System Parent Form (BESS Parent; Kamphaus & Reynolds, 2007) is a recently developed instrument designed to identify behavioral and emotional risk in students. To describe the underlying factor structure for this instrument, exploratory (EFA) and confirmatory factor analyses (CFA) were conducted utilizing two subsets of a large, nationally-representative sample. The results of the EFA suggested that the BESS Parent contained a four-factor latent structure (i.e., Externalizing, Internalizing, Adaptive Skills, and Inattention), which was supported by CFA. Results support further investigation into utilizing four subscales in addition to an overall risk score; distributional and reliability information for the BESS Parent subscales is provided. Practical implications for school psychologists interested in early identification and directions for future research are discussed.     

Memory for multiple visual ensembles in infancy

The number of individual items that can be maintained in working memory is limited. One solution to this problem is to store representations of ensembles that contain summary information about large numbers of items (e.g., the approximate number or cumulative area of a group of many items). Here we explored the developmental origins of ensemble representations by asking whether infants represent ensembles and, if so, how many at one time. We habituated 9-month-old infants to arrays containing 2, 3, or 4 spatially intermixed colored subsets of dots, then asked whether they detected a numerical change to one of the subsets or to the superset of all dots. Experiment Series 1 showed that infants detected a numerical change to 1 of the subsets when the array contained 2 subsets but not 3 or 4 subsets. Experiment Series 2 showed that infants detected a change to the superset of all dots no matter how many subsets were presented. Experiment 3 showed that infants represented both the approximate number and the cumulative surface area of these ensembles. Our results suggest that infants, like adults (Halberda, Sires, & Feigenson, 2006), can store quantitative information about 2 subsets plus the superset: a total of 3 ensembles. This converges with the known limit on the number of individual objects infants and adults can store and suggests that, throughout development, an ensemble functions much like an individual object for working memory.     

A social relations model of observed family negativity and positivity using a genetically informative sample

The goal of this study was to investigate individual and relationship influences on expressions of negativity and positivity in families. Parents and adolescents were observed in a round-robin design in a sample of 687 families. Data were analyzed using a multilevel social relations model. In addition, genetic contributions were estimated for actor effects. Children showed higher mean levels of negativity and lower mean levels of positivity as actors than did parents. Mothers were found to express and elicit higher mean levels of positivity and negativity than fathers. Actor effects were much stronger than partner effects, accounting for between 18%-39% of the variance depending on the actor and the outcome. Genetic (35%) and shared environmental (19%) influences explained a substantial proportion of the actor effect variance for negativity. Dyadic reciprocities were lowest in dyads with a high power differential (i.e., parent-child dyads) and highest for dyads with equal power (sibling and marital dyads).     

Recognizing discrimination explicitly while denying it implicitly: Implicit social identity protection

Past research suggests that members of devalued groups recognize their groups are discriminated against. Do the implicit responses of members of these groups demonstrate the same pattern? We argue that they do not and that this is due to a motivated protection of members of devalued groups' social identity. Study 1 demonstrates that, at an explicit level African-Canadians recognize that their group is discriminated against, but at an implicit level African-Canadians think that most people like their group to a greater extent than do European-Canadians. Study 2 replicates this implicit finding with Muslim participants while demonstrating that, when affirmed, this group difference disappears. Study 3 demonstrates that implicit normative regard can predict collective action over and above implicit attitudes and explicit normative regard. The implications for changing the status quo are discussed.     

Recognizing creative leadership: Can creative idea expression negatively relate to perceptions of leadership potential?

Drawing on and extending prototype theories of creativity and leadership, we theorize that the expression of creative ideas may diminish judgments of leadership potential unless the charismatic leadership prototype is activated in the minds of social perceivers. Study 1 shows that creative idea expression is negatively related to perceptions of leadership potential in a sample of employees working in jobs that required creative problem solving. Study 2 shows that participants randomly instructed to express creative solutions during an interaction are viewed as having lower leadership potential. A third scenario study replicated this finding showing that participants attributed less leadership potential to targets expressing creative ideas, except when the “charismatic” leader prototype was activated. In sum, we show that the negative association between expressing creative ideas and leadership potential is robust and underscores an important but previously unidentified bias against selecting effective leaders.     

Resources versus respect: Social judgments based on targets' power and status positions

In two experiments, we investigate how individuals' levels of power and status interact to determine how they are perceived by others. We find that power and status have similar, positive, effects on judged dominance. We also find that power has a negative effect on perceived warmth, but status moderates this “power penalty”: high power without status is associated with low warmth, but power with status is judged warm. Consequently, we find high status individuals, regardless of power level, are perceived positively - dominant and warm - whereas high power-low status individuals are judged most negatively — dominant and cold (Experiments 1 and 2). As a result, perceivers expect positive interactions with high status individuals, but negative interactions with high power, low status individuals (Experiment 2). These findings provide insight into power and status social judgments, and further our understanding of similarities and differences between these distinct, yet related, constructs.
