Temporal reproduction: further evidence for two processes

Some authors have suggested separate mechanisms for the processing of temporal intervals above versus below 2-3s. Given that the evidence is mixed, the present experiment was carried out as a critical test of the separate-mechanism hypothesis. Subjects reproduced five standard durations of 1-5s presented in the auditory and visual modalities. The Corsi-block test was used to assess effects of working-memory span on different interval lengths. Greater working-memory span was associated with longer reproductions of intervals of 3-5s. A factor analysis run on mean reproduced intervals revealed one modality-unspecific factor for durations of 1-2s and two modality-specific factors for longer intervals. These results are interpreted as further indications that two different processes underlie temporal reproductions of shorter and longer intervals.     

Avengers,assemble the literature! A multi-study review of consumption,environmental values,and planetary health research

Mother Earth is dying. Humanity needs to step up. Otherwise, the planet we call home will soon be uninhabitable. The destiny of our planet inarguably depends on consumers, as their choices have the power to turn them into eco-superheroes (sustainable consumption) or eco-villains (unsustainable consumption). This article aims to review the current progress of consumption research and propose strategies to inspire consumers to embrace their inner eco-warrior spirit, fostering sustainable behavior that protects the environment and supports human well-being. To achieve this, this article employs an integrative approach, merging a meta-perspective on theoretical development with a multi-study methodological approach. Harnessing the power of scientometrics, this article delivers meta-insights from a multi-study analysis on consumption trends in relation to environmental values (micro-perspective; Study 1) and planetary health (macro-perspective; Study 2). These findings pave the way for future research and intervention strategies designed to nurture ecological sustainability and unleash the eco-warrior in every consumer.     

Mechanisms of modal and amodal interpolation

P. J. Kellman and T. F. Shipley (1992) and P. J. Kellman, P. Garrigan, and T. F. Shipley (2005) suggested that completion of partly occluded objects and illusory objects involve the same or similar mechanisms at critical stages of contour interpolation. B. L. Anderson, M. Singh, and R. W. Fleming and B. L. Anderson (2007) presented a number of arguments against this view. The author analyzes 3 of these arguments, as well as B. L. Anderson's ecological justification for believing that these mechanisms must be very different, and suggests that their conclusions are unwarranted. The author also outlines a model consistent with the identity hypothesis and with recent physiological evidence, including a quantitative proposal for contour interpolation strength. The model suggests that V1 and V2 receive from higher visual areas feedback that modulates their responses to stimuli eliciting modal completion, amodal completion, and collinear contour facilitation. The model qualitatively explains the unstable percepts evoked by various recently devised stimuli.     

Associative processes in immediate recency

Some theorists have argued that the immediate recency effect observed in free recall reflects the emptying out of the contents of a short-term memory buffer (Davelaar, Goshen-Gottstein, Ashkenazi, Haarmann, & Usher, 2005). Others have argued that immediate recency reflects the properties of temporal context used to cue free recall (Howard & Kahana, 2002). We examined immediate free recall of lists with an item from the middle of the list repeated at or near the end. If associative processes contribute to immediate recency, as predicted by the temporal context account, the neighbors of the initial presentation of the repeated item should show enhanced recall at the initial stages of immediate recall. Recall transitions early in output--and even the initiation of recall itself-showed evidence for temporally defined associations that resemble those observed in recall from long-term memory. These results have strong implications for models of the immediate recency effect in free recall.     

Domestic violence and psychopathic traits: distinguishing the antisocial batterer from other antisocial offenders

The proliferation of specialized domestic batterer treatment programs suggests that batterers differ from other offenders in important ways. The psychopathic personality represents a constellation of personality traits, which may be relevant to the differentiation of batterers from other offenders. In a sample of 172 county jail inmates, we examined whether antisocial batterers can be distinguished from the larger pool of antisocial offenders on the basis of the four-facet model of psychopathy identified for the Psychopathy Checklist-Revised (PCL-R). Batterer/non-batterer status was positively related to the PCL-R affective facet and negatively related to the lifestyle facet, but there was no significant relationship between PCL-R total scores and this criterion. Results suggest that antisocial batterers are characterized by deficient affective experience and by reduced impulsivity and irresponsibility compared with other antisocial offenders. Implications are discussed in light of specialized treatments for batterers.     

Motion misperception caused by feedback connections: A neural model simulating the Fröhlich effect

When asked to indicate the starting position of a fast moving stimulus, observers do not indicate the actual starting position but a later position on the motion trajectory. This perceptual illusion is known as the “Fröhlich effect”. We present a neural model aimed at simulating this phenomenon based on feedforward and feedback connections. The basic simulation mechanisms seem to be compatible with the attentional and the motion extrapolation account. A comparison between simulated and empirical results showed that the model is capable of generating the same main effects as those found in the empirical data.     

Contribution of content, context, and process to understanding openness to organizational change: two experimental simulation studies

The authors examined the contribution of the content, context, and process of organizational transformation to employees' openness to change. The authors predicted that 5 factors would have a positive effect on openness to change: (a) threatening character of organizational change (content related), (b) trust in executive management (context related), (c) trust in the supervisor (context related), (d) history of change (context related), and (e) participation in the change effort (process related). The authors tested their hypotheses in 2 separate studies (N = 828 and N = 835) using an experimental simulation strategy. The first study crossed 4 variables in a completely randomized 2 x 2 x 2 x 2 factorial design. Results showed significant main effects for content, context, and process but no significant interaction effects. A second study, with a completely randomized 2 x 2 factorial design, crossed two context variables. Results showed a significant main and an interaction effect: Openness to change decreased dramatically only when history of change and trust in executive management were low.     

Individual differences in executive function partially explain the socioeconomic gradient in middle‐school academic achievement

Children from families with low socioeconomic status (SES) earn lower grades, perform worse on achievement tests, and attain less education on average than their peers from higher‐SES families. We evaluated neurocognitive mediators of SES disparities in achievement in a diverse sample of youth whose data were linked to administrative records of performance on school‐administered tests of 7th grade reading and math proficiency (N = 203). We used structural equation modeling to evaluate whether associations between SES (measured at ages 8–9) and achievement (measured at age 13) are mediated by verbal ability and executive function (measured at age 10), a suite of top‐down mental processes that facilitate control of thinking and behavior. Children from relatively higher‐SES families performed better than their lower‐SES peers on all neurocognitive and achievement measures, and SES disparities in both reading and math achievement were partially mediated by variation in executive function, but not verbal ability. SES disparities in executive function explained approximately 37% of the SES gap in math achievement and 17% of the SES gap in reading achievement. Exploratory modeling suggests that SES‐related variation in working memory may play a particularly prominent role in mediation. We discuss potential implications of these findings for research, intervention programming, and classroom practice.

A Randomized Comparison of Two Psychosocial Interventions on Family Functioning in Adolescents with Bipolar Disorder

Impairments in family functioning are associated with more severe depressive and manic symptoms, earlier recurrences, and more suicidal behaviors in early-onset bipolar disorder. This study examined whether family-focused treatment for adolescents (FFT-A) with BD I or II disorder led to greater increases in family cohesion and adaptability and decreases in conflict over 2 years compared to a briefer psychoeducational treatment (enhanced care, EC). Participants were 144 adolescents (mean age: 15.6 ± 1.4 years) with BD I or II with a mood episode in the previous 3 months. Adolescents and parents were randomized to either FFT-A (21 sessions) or EC (three sessions). Patients received guideline-based pharmacotherapy throughout the 2-year study. Trajectories of adolescent- and parent-rated family cohesion, adaptability, and conflict were analyzed over 2 years. FFT-A had greater effects on adolescent-rated family cohesion compared to EC over 2 years. Participants in FFT-A and EC reported similar improvements in family conflict across the 2 years. In the FFT-A group, low-conflict families had greater adolescent-rated family cohesion throughout the study compared to high-conflict families. High-conflict families in both treatment groups tended to show larger reductions in conflict over 2 years than low-conflict families. Family psychoeducation and skills training may improve family cohesion in the early stages of BD. Measuring levels of family conflict at the start of treatment may inform treatment responsiveness among those receiving FFT-A.
