Effects of three types of noncontingent auditory stimulation on vocal stereotypy in children with autism

We evaluated the effects of 3 types of noncontingent auditory stimulation (music, white noise, recordings of vocal stereotypy) on 2 children with autism who engaged in high rates of vocal stereotypy. For both participants, the music condition was the most effective in decreasing vocal stereotypy to near-zero levels, resulted in the highest parent social validity ratings, and was selected as most preferred in treatment preference evaluations.     

“This is My Community”: Reproducing and Resisting Boundaries of Exclusion in Contested Public Spaces

The way that public space is structured has significant implications for identity, social interaction, and participation in society. For those experiencing homelessness, with no or limited private space, survival hinges on the accessibility and livability of public space. However, the increasing privatization of public space in the United States has contributed to the implementation of anti‐homeless ordinances in cities, restricting sitting, standing, panhandling, and sleeping in public. This study analyzes data from interviews with housed and unhoused community members, text from a local policy document, and ethnographic observations to explore how boundaries between “insiders” and “outsiders” are drawn in public space and mediated through individual discourse. Our findings suggest that boundaries of exclusion are constructed through dominant narratives that portray the unhoused as a threat to safety and economic vitality, thus justifying the need for regulation and punishment through the criminalization of homelessness. Yet, informants also demonstrate resistance to this narrative by discussing how criminalization of homelessness perpetuates dehumanization, violence, and economic inequality. Policy implications for the regulation of public space are discussed.     

Subjective socioeconomic status and departmental identity interact to reduce depressive tendencies and negative affective responding for female undergraduates

How do subjective socioeconomic status (SES) and departmental identity promote the mental health of female undergraduates? We conducted a questionnaire study (Study 1) and an experimental study (Study 2) with undergraduates enrolled in a women's junior college to examine whether subjective SES and group identity have an interactive effect on mental health. Results indicated that in participants with high subjective SES, increased identification with their reference in‐group (the academic department) was associated with a decreased tendency for depression (Study 1). These individuals also showed reduced negative affect when responding in situations of social exclusion (Study 2). These effects were absent, or had a reduced intensity in participants with low subjective SES. In sum, subjective SES and departmental identity interact to reduce depressive tendencies and negative affective responding for female undergraduates. Individuals with higher subjective SES may gain more benefits from group identity. We have discussed the implications of these findings.     

The competitive reaction time task: The development and scientific utility of a flexible laboratory aggression paradigm

Laboratory measures play an important role in the study of aggression because they allow researchers to make causal inferences. However, these measures have also been criticized. In particular, the competitive reaction time task (CRTT) has been criticized for allowing aggression to be operationalized in multiple ways, leaving it susceptible to “p-hacking.” This article describes the development of the CRTT and the ways in which its paradigm flexibility and analytic flexibility allows it to test a wide range of hypotheses and research questions. This flexibility gives the CRTT significant scientific utility, but as with any research paradigm, comes with the obligation that it has to be used with integrity. Although safeguards exist and there is little evidence of misuse, study preregistration can increase confidence in CRTT findings. The importance of findings such as those of Hyatt et al. (in press), which provide further evidence for the validity of the CRTT, are also noted.     

How the disadvantaged appraise group-based exclusion: The path from legitimacy to illegitimacy

Although many forms of differential treatment based on group membership are perceived to be legitimate, disadvantaged group members’ responses to discrimination have been studied primarily in contexts in which such treatment is appraised as illegitimate. This has resulted in an impoverished understanding of differential group-based treatment and a failure to illuminate the processes by which discrimination can shift from being seen as legitimate to being viewed as illegitimate. We discuss the determinants of disadvantaged group members’ legitimacy appraisals and the de-legitimisation process, whereby forms of discrimination appraised as legitimate come to be increasingly perceived as illegitimate. Whether group-based exclusion is addressed collectively or individually depends on socio-structural factors such as the pervasiveness of discrimination, impermeability of intergroup boundaries, and the availability of cognitive alternatives to the status quo. We conclude that understanding the antecedents and consequences of legitimacy appraisals is necessary to develop a comprehensive account of disadvantaged group members’ experiences of group-based discrimination.     

Does it help to feel your body? Evidence is inconclusive that interoceptive accuracy and sensibility help cope with negative experiences

ABSTRACT

In four studies (total N?=?534), we examined the moderating impact of Interoceptive Accuracy (i.e. IAcc, as measured with the heartbeat counting task) and Interoceptive Sensibility (IS, assessed via questionnaire) on negative affect, following social exclusion or after receiving negative feedback. Results from an integrative data analysis combining the four studies confirmed that the manipulations were successful at inducing negative affect. However, no significant interaction between mood induction (control versus negative affect induction) and interoception on mood measures was observed, and this was true both for objective (i.e. IAcc) and subjective (i.e. IS) measures of interoception. Hence, previous conclusions on the moderating impact of interoception in the relationship between mood induction and self-reported mood were neither replicated nor generalised to this larger sample. We discuss these findings in light of theories of emotion regulation as well as recent concerns raised about the validity of the heartbeat counting task.     

Cognitive-emotional dysfunction among noisy minds: Predictions from individual differences in reaction time variability

Mental noise can be defined as less reliable information processing. Individuals with high levels of mental noise are thought to be disadvantaged in cognitive, emotional, and behavioural realms. The present five studies (total N=298) investigated such potential disadvantages among normally functioning college undergraduates. Mental noise was operationalised in terms of the reaction time coefficient of variation (RTCV), a measure of RT variability that corrects for average levels of mental speed. Individuals with higher RTCV exhibited less effective cognitive control (Studies 1 and 5), less controlled behaviour (Study 2), and were more prone to negative emotional experiences (Study 3) and depressive symptoms (Study 4). Study 5 extended these results and found that individuals higher (versus lower) in RTCV were more adversely affected by their attentional lapses in daily life. Results converge on the idea that mental noise is an important individual difference dimension with multiple adverse correlates and consequences.     

Brief pitch-priming facilitates infants’ discrimination of pitch-evoking noise: Evidence from event-related potentials

Pitch is derived by the auditory system through complex spectrotemporal processing. Pitch extraction is thought to depend on both spectral cues arising from lower harmonics that are resolved by cochlear filters in the inner ear, and on temporal cues arising from the pattern of action potentials contained in the cochlear output. Adults are capable of extracting pitch in the absence of robust spectral cues, taking advantage of the temporal cues that remain. However, recent behavioral evidence suggests that infants have difficulty discriminating between stimuli with different pitches when resolvable spectral cues are absent. In the current experiments, we used the mismatch negativity (MMN) component of the event related potential derived from electroencephalographic (EEG) recordings to examine a cortical representation of pitch discrimination for iterated rippled noise (IRN) stimuli in 4- and 8-month-old infants. IRN stimuli are pitch-evoking sounds generated by repeatedly adding a segment of white noise to itself at a constant delay. We created IRN stimuli (delays of 5 and 6 ms creating pitch percepts of 200 and 167 Hz) and high-pass filtered them to remove all resolvable spectral pitch cues. In experiment 1, we did not find EEG evidence that infants could detect the change in the pitch of these IRN stimuli. However, in Experiment 2, after a brief period of pitch-priming during which we added a sine wave component to the IRN stimulus at its perceived pitch, infants did show significant MMN in response to pitch changes in the IRN stimuli with sine waves removed. This suggests that (1) infants can use temporal cues to process pitch, although such processing is not mature and (2) that a short amount of pitch-priming experience can alter pitch representations in auditory cortex during infancy.     

A non-auditory measure of interference predicts distraction by competing speech in older adults

ABSTRACT

In this study, older adults monitored for pre-assigned target sounds in a target talker's speech in a quiet (no noise) condition and in a condition with competing-talker noise. The question was to which extent the impact of the competing-talker noise on performance could be predicted from individual hearing loss and from a cognitive measure of inhibitory abilities, i.e., a measure of Stroop interference. The results showed that the non-auditory measure of Stroop interference predicted the impact of distraction on performance, over and above the effect of hearing loss. This suggests that individual differences in inhibitory abilities among older adults relate to susceptibility to distracting speech.     

Understanding of moral emotions and social exclusion in pre-schoolers and third graders

Abstract

This study examined whether children use information about moral emotions when judging peer exclusion. Japanese pre-schoolers and third graders (N = 110) listened to stories featuring characters who felt happy or sad after engaging in immoral behaviour or avoiding immoral behaviour (pushing a child off a swing and stealing another child’s doughnuts). In study 1, participants judged the extent to which characters who felt happiness, guilt, and pride would be socially excluded. In study 2, participants judged whether characters who felt guilt, no guilt, pride, and no pride would be socially excluded. Participants believed that characters would be socially excluded based on moral emotions. Characters who did not feel guilt or pride were excluded more frequently relative to those who did; however, children found it easier to judge exclusion based on guilt rather than pride, especially in the case of pre-schoolers. Moreover, pre-schoolers had difficulty explaining their reasoning.
