Recall-to-reject: The effect of category cues on false recognition

Four experiments examined the effect of category cueing on recall-to-reject, one of the central memory-editing mechanisms thought to prevent the occurrence of false memories. When category names were used as retrieval cues, the typically observed false recognition effect was eliminated for semantically associated distractors (Experiment 1a) and, moreover, a reduction in the absolute level of the false alarm rate was found for phonologically associated distractors (Experiment 2a). In addition to the old/new-recognition data, analyses using multinomial models support the interpretation that category cueing was successful in increasing the probability of recall-to-reject (Experiments 1b and 2b). The results are in line with dual-process theories of recognition memory and provide further evidence for recall-to-reject in single item recognition. They demonstrate its potential to reduce false recognition even when explicit instructions are not given. In addition, the results demonstrate that the paradigm can give rise to side effects that oppose recall-to-reject. A simultaneous familiarity increase can explain why many studies failed to find evidence for recall-to-reject in terms of false alarm rates.     

Wanting to Be Boss and Wanting to Be Subordinate: Effects on Performance Motivation

Does dyad members' motivation to take on a high or low power position influence the dyad's performance motivation when assigned to hierarchical roles? Participants in 69 dyads (33 all‐women, 36 all‐men) indicated whether they preferred the high‐power role (owner of an art gallery) or the low power role (assistant to the owner). Power roles were then randomly assigned. The dyad's interaction during task solving was videotaped. Uninvolved coders rated performance motivation as the degree of quality of the superior's and the subordinate's task contributions and effort put into the task. Performance motivation was better if the boss preferred the high power to the low power role, irrespective of the subordinate's role preference. Leadership effectiveness is thus affected by the superior's power motivation.     

Making and Unmaking Prejudice: Religious Affiliation Mitigates the Impact of Mortality Salience on Out‐Group Attitudes

Research inspired by terror management theory has established that being reminded of the inevitability of death (i.e., “mortality salience”) leads people to express more negative attitudes toward out‐groups. We examined the hypothesis that being affiliated with a religion may buffer individuals against this negative impact of mortality salience. Two studies, conducted in two cultures that differ in their emphasis on religiosity (the United Kingdom and Italy), supported this hypothesis. Specifically, we found that mortality salience resulted in more negative out‐group attitudes only among participants not affiliated with any religion. Further, this buffering effect of religious affiliation was not moderated by participants’ specific religious orientations or by their levels of social dominance orientation. In addition, the buffering effect did not hold when prejudice against the target out‐group was not proscribed by religious authorities. Implications for research on religion, prejudice, and terror management are discussed.     

Construing multiple ingroups: Assessing social identity inclusiveness and structure in ethnic and religious minority group members

The combination of multiple social identities into a coherent ingroup construal is of immediate relevance in today's complex and diverse societies. This paper proposes a conceptual and operational framework to examine how individuals subjectively construe their ingroup in the context of multiple, cross‐cutting group memberships. The subjective combination of multiple social identities is described in terms of structure (social identity structure) and inclusiveness (social identity inclusiveness (SII)). Two studies assess SII and social identity structure in community samples to whom the subjective combination of multiple, cross‐cutting ingroups is of particular relevance: a sample of Turkish‐Belgian Muslims (Study 1) and Turkish‐Australian Muslims (Study 2). Across both studies, SII uniquely predicted attitudes toward a range of outgroups, over and above identification with singular ingroups. Moreover, a wide range of social identity structures were identified, further attesting to broad individual differences in the construal of the perceived ingroup.

Nonsuicidal Self-Injury in Adolescents Placed in Youth Welfare and Juvenile Justice Group Homes: Associations with Mental Disorders and Suicidality

Nonsuicidal self-injury (NSSI) is a frequent phenomenon in adolescents, however there is a lack of studies on the prevalence of NSSI in adolescents placed in youth welfare and juvenile justice group homes. The goal of the present study is to investigate the prevalence rates of NSSI and mental disorders in adolescents living in the youth welfare system, as well as how occasional and repetitive NSSI differ with respect to mental disorders, suicidality, and gender. The sample consisted of 397 adolescents aged 12 to19 years (mean age = 15.98, SD = 1.77, 65.7% male) placed in youth welfare and juvenile justice group homes. NSSI, suicidality, and mental disorders were assessed using the Kiddie-Schedule of Affective Disorders and Schizophrenia (K-SADS-PL). Lifetime prevalence rates of occasional and repetitive NSSI were 21.9% and 18.4%, respectively and 85.6% of the sample endorsed a lifetime mental disorder. Occasional and repetitive NSSI were significantly associated with depressive, conduct, and substance use disorders (d = 0.50–0.67) among both genders. Prevalence rates of repetitive NSSI in youth welfare and juvenile justice institutions are higher than in the general population and males who engage in NSSI are at particularly high risk of suicidality. Due to the high prevalence of NSSI and its related problems, NSSI should be routinely assessed in this vulnerable population and staff should be trained in recognizing and handling NSSI as well as supporting adolescents in improving their emotion regulation skills.     

Adaptation to continuous perturbation of balance: progressive reduction of postural muscle activity with invariant or increasing oscillations of the center of mass depending on perturbation frequency and vision conditions

We investigated the adaptation of balancing behavior during a continuous, predictable perturbation of stance consisting of 3-min backward and forward horizontal sinusoidal oscillations of the support base. Two visual conditions (eyes-open, EO; eyes-closed, EC) and two oscillation frequencies (LF, 0.2 Hz; HF, 0.6 Hz) were used. Center of Mass (CoM) and Center of Pressure (CoP) oscillations and EMG of Soleus (Sol) and Tibialis Anterior (TA) were recorded. The time course of each variable was estimated through an exponential model. An adaptation index allowed comparison of the degree of adaptation of different variables. Muscle activity pattern was initially prominent under the more challenging conditions (HF, EC and EO; LF, EC) and diminished progressively to reach a steady state. At HF, the behavior of CoM and CoP was almost invariant. The time-constant of EMG adaptation was shorter for TA than for Sol. With EC, the adaptation index showed a larger decay in the TA than Sol activity at the end of the balancing trial, pointing to a different role of the two muscles in the adaptation process. At LF, CoM and CoP oscillations increased during the balancing trial to match the platform translations. This occurred regardless of the different EMG patterns under EO and EC. Contrary to CoM and CoP, the adaptation of the muscle activities had a similar time-course at both HF and LF, in spite of the two frequencies implying a different number of oscillation cycles. During adaptation, under critical balancing conditions (HF), postural muscle activity is tuned to that sufficient for keeping CoM within narrow limits. On the contrary, at LF, when vision permits, a similar decreasing pattern of muscle activity parallels a progressive increase in CoM oscillation amplitude, and the adaptive balancing behavior shifts from the initially reactive behavior to one of passive riding the platform. Adaptive balance control would rely on on-line computation of risk of falling and sensory inflow, while minimizing balance challenge and muscle effort. The results from this study contribute to the understanding of plasticity of the balance control mechanisms under posture-challenging conditions.     

Health-Related Quality of Life is Associated with Positive Affect in Patients with Coronary Heart Disease Entering Cardiac Rehabilitation

Health-related quality of life (QoL) is an important and widely used outcome measure in cardiac populations. We examined the relationship between positive affect and health-related quality of life, controlling for traditional cardiovascular risk factors, clinical variables and negative affect. We further investigated the role of gender in this relationship given the well-known gender differences in cardiovascular health. We enrolled 746 patients with coronary heart disease (CHD) before they entered outpatient cardiac rehabilitation. All patients completed the Global Mood Scale and the SF-36 Health Survey. Positive affect was independently associated with mental (p < .001) and physical QoL (p < .001) after controlling for control variables. Gender moderated the relationship between positive affect and physical QoL (p = .009) but not mental QoL (p = .60). Positive affect was positively associated with physical QoL in men (p < .001) but not in women (p = .44). The health-related QoL of patients with CHD is associated with a person’s level of positive affect.

A simultaneous familiarity increase can explain why many studies failed to find evidence for recall-to-reject in terms of false alarm rates.     

Women's advantage at remembering others' appearance: A systematic look at the why and when of a gender difference

Women recall the appearance of others better than men. The goal of the present research was to shed light on the explanations and boundary conditions of this gender difference. In three studies (592 participants), the authors tested potential mediators and moderators of the gender difference. Results corroborated the robustness of the gender difference. General task motivation, general memory ability, importance of appearance, appearance knowledge, attention paid to target, gazing at target, and communal or agentic orientation could not explain why women were better at recalling others' appearance than men were. Except for importance of appearance and appearance knowledge, which both decreased the magnitude of the gender difference, general task motivation, attention paid to target, length of exposure to target, delay in responding, cognitive load, and response format (verbal vs. nonverbal) had no effect on the gender difference. Results are discussed in relation to gender differences found in the nonverbal sensitivity literature.     

Performance in picture naming and word comprehension: evidence for common neuronal substrates from intraoperative language mapping

Correlations of naming ability and performance in the Token Test are known from aphasia; however, the mechanisms underlying these correlations are unclear. Naming tasks are commonly used in intraoperative mapping for identification of cortical areas involved in language processing. In the present study, we measured performance in an elementary Token Test task, i.e., single word comprehension, during electrical stimulation of cortical sites at which this stimulation previously had disturbed the naming process. It was found that at about half of the sites at which naming could be disturbed electrical stimulation also led to disturbances in Token Test performance, indicating that there are common neural structures critical for performance in both tasks. These findings are discussed in terms of a multilayered semantic network in which the level of the simultaneous binding of features into concepts and the level of units that are organized with respect to semantic relations may be disturbed separately.
