Similar patterns of age-related differences in emotion recognition from speech and music

Young and old adults’ ability to recognize emotions from vocal expressions and music performances was compared. The stimuli consisted of (a) acted speech (anger, disgust, fear, happiness, and sadness; each posed with both weak and strong emotion intensity), (b) synthesized speech (anger, fear, happiness, and sadness), and (c) short melodies played on the electric guitar (anger, fear, happiness, and sadness; each played with both weak and strong emotion intensity). The listeners’ recognition of discrete emotions and emotion intensity was assessed and the recognition rates were controlled for various response biases. Results showed emotion-specific age-related differences in recognition accuracy. Old adults consistently received significantly lower recognition rates for negative, but not for positive, emotions for both speech and music stimuli. Some age-related differences were also evident in the listeners’ ratings of emotion intensity. The results show the importance of considering individual emotions in studies on age-related differences in emotion recognition.     

Mother‐child interaction is associated with neurocognitive outcome in extremely low gestational age children

Early mother‐child interaction is one of the factors suggested to have an impact on neurocognitive development of extremely low gestational age (ELGA) children. Our aim was to examine associations of mother‐child interaction with neurocognitive outcome, neurological impairments and neonatal brain injuries in ELGA children. A prospective study of 48 ELGA children, born before 28 gestational weeks (26.3 ± 1.2 weeks, birth weight 876 g ± 194 g), and 16 term controls. Brain MRI was performed at term‐equivalent age. At two years of corrected age, the mother‐child interaction was assessed in a structured play situation using the Erickson Scales and Mutually Responsive Orientation Scales. Neurocognitive outcome was assessed with Griffiths Mental Developmental Scales (GMDS) and Bayley Scales of Infant and Toddler Development ‐ Third Edition (BSID‐III) and with Hempel neurological examination. Among ELGA children, higher quality of dyadic relationship and maternal sensitivity, responsiveness, and supportiveness were associated with positive neurocognitive outcome measured both with GMDS and BSID‐III (adjusted p < 0.05). This association remained after adjusting for mother's educational level. Neurological impairments at two years, white matter or gray matter abnormalities in MRI at term‐equivalent age, and grade III‐IV intraventricular hemorrhage during the neonatal period were not associated with mother‐child interaction. This study emphasizes the importance of the quality of mother‐child interaction after extremely preterm birth for neurocognitive development. Neonatal brain injury and neurological impairments were not associated with worse parent‐child interaction after two years.     

Attention‐shift vs. response‐priming explanations for the spatial cueing effect in cross‐modal tasks

The task‐irrelevant spatial location of a cue stimulus affects the processing of a subsequent target. This “Posner effect” has been explained by an exogenous attention shift to the spatial location of the cue, improving perceptual processing of the target. We studied whether the left/right location of task‐irrelevant and uninformative tones produces cueing effects on the processing of visual targets. Tones were presented randomly from left or right. In the first condition, the subsequent visual target, requiring response either with the left or right hand, was presented peripherally to left or right. In the second condition, the target was a centrally presented left/right‐pointing arrow, indicating the response hand. In the third condition, the tone and the central arrow were presented simultaneously. Data were recorded on compatible (the tone location and the response hand were the same) and incompatible trials. Reaction times were longer on incompatible than on compatible trials. The results of the second and third conditions are difficult to explain with the attention‐shift model emphasizing improved perceptual processing in the cued location, as the central target did not require any location‐based processing. Consequently, as an alternative explanation they suggest response priming in the hand corresponding to the spatial location of the tone. Simultaneous lateralized readiness potential (LRP) recordings were consistent with the behavioral data, the tone cues eliciting on incompatible trials a fast preparation for the incorrect response and on compatible trials preparation for the correct response.     

Changes in Female Rape Myth Acceptance Among College Students: A 20-Year Perspective

In this study, we compared changes in female rape myth acceptance (RMA) between 1998 and 2018 in two separate samples of college students from the same university in the U.S. Pacific Northwest. The primary measure was the Attitudes Toward Rape Victims Scale (ARVS). First, we examined the factor structure of the ARVS with confirmatory factor analysis, finding good fit for a four-factor model comprising Assigning Blame or Responsibility to the Victim (Blame/Responsibility), Considering the Victim as Deserving of Sexual Violence (Deserving), Undermining the Victim’s Credibility (Undermine Credibility), and Trivializing the Experience or Denigrating the Victim (Trivialization/Denigration). Second, we used profile analysis, a type of multivariate repeated-measures ANOVA, to examine the main and interactive effects of Survey Year, Gender, and ARVS Subscale and Item within each subscale. At the subscale level, we found large main effects for Survey Year, Gender, and Subscale, with lower scores for the 2018 sample, women, and Deserving and Trivialization/Denigration, relative to Undermine Credibility and Blame/Responsibility. We also found interactions between Survey Year and Subscale and Gender and Subscale, indicating non-parallel profiles for the 1998 versus 2018 samples and women versus men. We found similar patterns at the item level within each subscale. These results indicate a substantial decline of female RMA in college students over a 20-year period, replicate the well-established gender difference in female RMA, and demonstrate that RMA varies by item content.

     

SOCIAL PHOBIA: CONTROL PROCESSES IN ANXIETY-PROVOKING SITUATIONS

Control of anxiety-related emotions in anxiety-provoking situations was qualitatively examined for 21 social phobic clients before treatment. A model illustrating the functional coherence of the control processes across those situations was constructed, based on narratives of problematic situations. Results indicated that the model reflects fundamental processes in social phobia, possibly resulting from early attachment. In addition, three groups were identified that differed in respect to control-activity. These results indicate that the differences reflect surface variation of processing, resulting from development and interaction in adolescence and adulthood. Both the coherence and the variation should be taken into account when dealing with and developing treatment procedures for social phobics.     

Adolescents' implicit theories predict desire for vengeance after peer conflicts: correlational and experimental evidence

Why do some adolescents respond to interpersonal conflicts vengefully, whereas others seek more positive solutions? Three studies investigated the role of implicit theories of personality in predicting violent or vengeful responses to peer conflicts among adolescents in Grades 9 and 10. They showed that a greater belief that traits are fixed (an entity theory) predicted a stronger desire for revenge after a variety of recalled peer conflicts (Study 1) and after a hypothetical conflict that specifically involved bullying (Study 2). Study 3 experimentally induced a belief in the potential for change (an incremental theory), which resulted in a reduced desire to seek revenge. This effect was mediated by changes in bad-person attributions about the perpetrators, feelings of shame and hatred, and the belief that vengeful ideation is an effective emotion-regulation strategy. Together, the findings illuminate the social-cognitive processes underlying reactions to conflict and suggest potential avenues for reducing violent retaliation in adolescents.     

The role of unattended distractors in sustained inattentional blindness

When participants are attending to a subset of visual targets or events and ignoring irrelevant distractors (“selective looking”), they often fail to detect the appearance of an unexpected visual object or event even when the object is visible for several seconds (“sustained inattentional blindness”). An important factor influencing detection rates in selective looking is the attentional set of the participant: the more similar the features of the unexpected object are to the attended ones, the more probably it will be detected. We examined the possible contribution of active ignoring to this similarity effect by studying the role of the distractor objects in sustained inattentional blindness. First we showed the similarity effect for chromatic colors and then we manipulated the similarity of the unexpected object in relation to the distractor objects and did not find any effects. Moreover, we found that inattentional blindness was present even when the displays did not contain any irrelevant to-be-ignored objects. We conclude that attending to target items on the basis of attentional set, but not active ignoring of nontargets items, is sufficient for the occurrence of sustained inattentional blindness.     

The role of attention in subitizing

The process of rapidly and accurately enumerating small numbers of items without counting, i.e. subitizing, is often believed to rest on parallel preattentive processes. However, the possibility that enumeration of small numbers of items would also require attentional processes has remained an open question. The present study is the first that directly contrasts the preattentive and attentive models of subitizing. We used an inattentional blindness paradigm to manipulate the availability of attentional resources during enumeration. In the inattention condition, the items to be enumerated were presented unexpectedly while participants focused on a line length comparison task. Divided- and full-attention conditions were also included. The results showed that only numbers one and two could be enumerated when the effects of attention were minimized. Freeing attentional resources increased the enumeration accuracies considerably, including for number two. The results suggest that even for enumerating small numbers, the attentional demands increase as the number of objects increases.     

The electrophysiological correlates of stimulus visibility and metacontrast masking

There are conflicting views concerning the electrophysiological correlates of visual consciousness. Whereas one view considers a relatively late positive deflection (LP) as a primary correlate of consciousness, another model links consciousness with earlier negativity (VAN). The present experiment utilized metacontrast masking in investigating the electrophysiological correlates of visual consciousness. The participants were presented with target-mask sequences in three stimulus onset asynchronies. The target stimuli were followed by either a metacontrast mask or a similar-looking, but ineffective pseudomask. The results showed that the first deflection that correlated with target visibility was VAN which was followed by LP. We argue that the VAN is the primary correlate target visibility, while the LP reflects later, postperceptual processing stages.
