Perceiving vocal age and gender: An adaptation approach

Aftereffects of adaptation have revealed both independent and interactive coding of facial signals including identity and expression or gender and age. By contrast, interactive processing of non-linguistic features in voices has rarely been investigated. Here we studied bidirectional cross-categorical aftereffects of adaptation to vocal age and gender. Prolonged exposure to young (~ 20 yrs) or old (~ 70 yrs) male or female voices biased perception of subsequent test voices away from the adapting age (Exp. 1) and the adapting gender (Exp. 2). Relative to gender-congruent adaptor-test pairings, vocal age aftereffects (VAAEs) were reduced but remained significant when voice gender changed between adaptation and test. This suggests that the VAAE relies on both gender-specific and gender-independent age representations for male and female voices. By contrast, voice gender aftereffects (VGAEs) were not modulated by age-congruency of adaptor and test voices (Exp. 2). Instead, young voice adaptors generally induced larger VGAEs than old voice adaptors. This suggests that young voices are particularly efficient gender adaptors, likely reflecting more pronounced sexual dimorphism in these voices. In sum, our findings demonstrate how high-level processing of vocal age and gender is partially intertwined.     

Activity experiences shape perceived fitness trajectories: Results from a 6-month randomized controlled trial in older women

ABSTRACT

In this study we addressed the subjective benefits of activity interventions that were designed to improve cognitive fitness in old age. Two hundred and fifty-nine women (aged 70–93 years) were randomized to participate in an exercise or a computer course or a control condition for 6 months. Subjective ratings of the perceived change of cognitive and physical fitness components were captured before, during, after the intervention interval, and at a 10-month follow-up. Positive and negative affect levels and objective cognitive fitness parameters served as possible covariates. Multilevel modeling revealed that the computer group rated memory and concentration as having improved at 4 months and again at 6 months. The exercise group, in contrast, perceived physical capacities as maintained or improved. The characteristics of the activity experience seem to determine the perceived fitness changes. We conclude that actual learning experiences improve one's self-concept of abilities.     

Preparing the Field for Feasibility Testing of a Parenting Intervention for War‐Affected Mothers in Northern Uganda

In this article, we discuss the successful implementation of an adapted evidence‐based parenting intervention for families affected by two decades of war in Northern Uganda. The adaptation and adoption of such interventions to support mental health and family functioning is widely endorsed by prevention scientists and considered a priority in global mental health. The preparation and early adoption phases of engaging with a highly vulnerable community affected by war trauma are documented in this paper along with a discussion of the steps taken to adapt a parenting intervention for cultural and contextual fit. This study is a component of an overall program of research aimed at reducing the long‐term negative effects of war on parenting practices and childhood outcomes, which have considerable implications for preventing mental, neurological, and substance‐use disorders. The processes described here cover a 4‐year period culminating in the implementation of the nine‐session Enhancing Family Connection intervention piloted with a group of 14 mothers. The lessons in cultural adaptation have been valuable and the feasibility results promising for further testing the intervention.     

The influence of natural contour and face size on the spatial frequency tuning for identifying upright and inverted faces

Psychological Research - It has previously been proposed that holistic face processing is based on low spatial frequencies (SFs) whereas featural processing relies on higher SFs, a hypothesis still...     

Keeping the Conversational Score: Constraints for an Optimal Contextualist Answer?

Conversational contextualism states that the truth-conditions expressed by knowledge-attributing sentences vary relative to the context of utterance. This context is determined partly by different standards the person involved must meet in order to make the sentence true. I am concerned with the question of how these standards can be raised or lowered, and especially what happens to the standards and the conversational score when parties in a discussion push the conversational scores in different directions. None of the available options for an answer seems satisfying. I argue that this results from a misunderstanding of the characteristics of the situation at hand.     

Wie arbeite ich wirklich mit einem Traum?

According to Jung major impulses for psychic development and therefore for dealing with conflicts accrue from the unconscious in the form of dreams. In this article it will be shown as clearly as possible how a dream was dealt with in the therapeutic relationship.     

Does performance on the standard antisaccade task meet the co-familiality criterion for an endophenotype?

The “co-familiality” criterion for an endophenotype has two requirements: (1) clinically unaffected relatives as a group should show both a shift in mean performance and an increase in variance compared with controls; (2) performance scores should be heritable. Performance on the antisaccade task is one of several candidate endophenotypes for schizophrenia. In this paper we examine whether the various measures of performance on the standard version of the antisaccade task meet the co-familiality criterion for an endophenotype. The three measures of performance—reflexive saccade errors, latency of correct antisaccades, and gain—show a wide range of effect sizes and variance ratios as well as evidence of significant or near significant heterogeneity. The estimated mean effect sizes [Cohen’s d: error rate: 0.34 (SD: 0.29); latency: 0.33 (SD: 0.30); gain: 0.54 (SD: 0.38)] are significantly greater than 0, but the magnitude of the departures from 0 is relatively small, corresponding to modest effect sizes. The width of the 95% confidence intervals for the estimated effect sizes (error rate: 0.2–0.49; latency: 0.17–0.50; gain: 0.23–0.85) and the coefficients of variation in effect sizes (error rate: 85.3%; latency: 90.9%; gain: 68.4%) reflect heterogeneity in effect sizes. The effect sizes for error rate showed statistically significant heterogeneity and those for latency (P = .07) and gain (P = .09) showed a trend toward heterogeneity. These results indicate that the effect sizes are not consistent with a single mean and that the average effect size may be a biased estimate of the magnitude of differences in performance between relatives of schizophrenics and controls. Relatives of schizophrenics show a small but significant increase in variance in error rate, but the confidence interval is broad, perhaps reflecting the heterogeneity in effect size. The variance ratios for latency and gain did not differ in relatives of schizophrenics and controls. Performance, as measured by error rate, is moderately heritable. The data do not provide compelling support for a consistent shift in mean or variance in relatives of schizophrenia patients compared with nonpsychiatric controls, both of which are required for a major gene involved in co-familial transmission. This set of findings suggests that although intra-familial resemblance in antisaccade performance is due in part to genetic factors, it may not be related to a schizophrenia genotype. Based on the current literature, it would be premature to conclude that any of the measures of antisaccade performance unambiguously meets the co-familiality criterion for an endophenotype.     

Gender differences in depressive symptomatology: The role played by “anxious somatic depression” associated with gender-related achievement concerns

In the studies reported here, females were more likely than males to report high levels of depression accompanied by anxiety and somatic symptomatology such as disordered eating and headache, but not more likely to report depression unaccompanied by these symptoms. This gender difference in depression prevalence and the symptomatology associated with depression was due to a subgroup of females who scored high on scales comprised of items measuring concerns about the limitations placed on their achievement (sample item: “More people would pay attention to my ideas if I were male”) or on their mothers (sample: “When you were growing up, how much did your mother feel limited by being female?”) due to responses to their gender.
