Time-shrinking: the process of unilateral temporal assimilation

Our previous research on auditory time perception showed that the duration of empty time intervals shorter than about 250 ms can be underestimated hugely if they are immediately preceded by shorter time intervals. We named this illusion 'time-shrinking' (TS). This study comprises four experiments in which the preceding interval, t1, was followed by a standard interval, t2. When t1 < or = 200 ms, and t1 < or = t2, the underestimation of t2 came into view clearly. The absolute difference between t2 and t1 was the crucial factor for the illusion to appear. The underestimation increased when t2 increased from t1 to t1 + 65 ms, stayed at about 45 ms when t2 was between t1 + 65 ms and t1 + 95 ms, and disappeared suddenly when t2 exceeded t1 + 95 ms. This pattern of results was observed across all values of t1 < or = 200 ms. A model was fit to the data to elucidate the underlying process of the illusion. The model states that the perceived duration difference between t1 and t2 is reduced by cutting mental processing time for t2; in other words, that t2 assimilates to t1.     

Childhood dental fear in relation to parental child-rearing attitudes

The aim of this study was to assess the relation between parental self-reported child-rearing attitudes and dental fear in children. The parents of 51 children with high dental fear and of 56 children with low dental fear, of different age groups, completed the Amsterdam version of the Parental Attitude Research Instrument. In addition, parents were asked to rate their own dental fear. Multivariate analysis of variance (child fear x parental fear x child age) showed a significant main effect only of child dental fear on parental self-complaints (p = .03). For parental dental fear, main effects were found on overprotection and on promotion of autonomy (p < or = .01). No age effects were found. Also, no relation between children's dental fear and parental dental fear was found. Based on the present findings, it was concluded that parents may play a more secondary, mediating role in the etiological process of dental fear in children.     

Illusory recouplings of onsets and terminations of glide tone components

We present a new auditory illusion, the gap transfer illusion, supported by phenomenological and psychophysical data. In a typical situation, an ascending frequency glide of 2,500 msec with a temporal gap of 100 msec in the middle and a continuously descending frequency glide of 500 msec cross each other at their central positions. These glides move at the same constant speed in logarithmic frequency in opposite directions. The temporal gap in the long glide is perceived as if it were in the short glide. The same kind of subjective transfer of a temporal gap can take place also when the stimulus pattern is reversed in time. This phenomenon suggests that onsets and terminations of glide components behave as if they were independent perceptual elements. We also find that when two long frequency glides are presented successively with a short temporal overlap, a long glide tone covering the whole duration of the pattern and a short tone around the temporal middle can be perceived. To account for these results, we propose an event construction model, in which perceptual onsets and terminations are coupled to construct auditory events and the proximity principle connects these elements.     

Real-life outgroup exposure,self-reported outgroup contact and the other-race effect

People are better at recognizing faces from their own racial or ethnic group compared with faces from other racial or ethnic groups, known as the other-‘race’ effect (ORE). Several theories of the ORE assume that memory for other-race faces is impaired because people have less contact with members of other racial or ethnic groups, resulting in lower visual expertise. The present research investigates contact theories of the ORE, using self-report contact measures and objective measures of potential outgroup exposure (estimated from participants' residential location and from GPS tracking). Across six studies (total N = 2660), we observed that White American and White German participants displayed better memory for White faces compared with Black or Middle Eastern faces, whereas Black American participants displayed similarly equal or better memory for White compared with Black faces. We did not observe any relations between the ORE and objective measures of potential outgroup exposure. Only in Studies 2a and 2b, we observed very small correlations (rs = −.08 to .06) between 4 out of 30 contact measures and the ORE. We discuss methodological limitations and implications for theories of the ORE.     

Effortless Self‐Control: A Novel Perspective on Response Conflict Strategies in Trait Self‐Control

Self‐control is of invaluable importance for well‐being. While previous research has focused on self‐control failure, we introduce a new perspective on self‐control, including the notion of effortless self‐control, and a focus on self‐control success rather than failure. We propose that effortless strategies of dealing with response conflict (i.e., competing behavioral tendencies) are what distinguishes successful self‐controllers from less successful ones. While people with high trait self‐control may recognize the potential for response conflict in self‐control dilemmas, they do not seem to subjectively experience this conflict as much as people with low self‐control. Two strategies may underlie this difference: avoidance of response conflict through adaptive, habitual behaviors, and the efficient downregulating of response conflict. These strategies as well as the role of response conflict are elaborated upon and discussed in the light of existing literature on self‐control.     

Relevance of the Tripartite Dimensions of Affect for Anxiety and Depression in Youth: Examining Sex and Psychopathology Status

Using a combined sample (N = 1,215) of referred children and children from the general population aged between 8 and 14 years, the present study addressed two research goals: First, latent mean differences (depending on the individual’s sex or psychopathology level) in anxiety, depression, Positive Affect (PA), Negative Affect (NA) and Physiological Hyperarousal (PH) were examined. Secondly, the structure of anxiety and depression was investigated from a tripartite model perspective in boys and girls with high versus low levels of psychopathology respectively. When relating the latent mean level differences in NA, PA, and PH with those in anxiety and depression, the results suggest that higher levels (depending on the individual’s sex and psychopathology status) of anxiety or depression are associated with higher levels of PH and lower levels of PA, whereas no consistent pattern was found between mean level differences in NA on the one hand and mean level differences in anxiety/depression on the other. Results further demonstrated that a better fit was obtained for the dual than for the unitary construct representation in boys or girls with high or low levels of psychopathology, thereby suggesting that a valid distinction can be made between anxiety and depression in children between 8 and 14 years old, irrespective of their sex or level of psychopathology. However, when looking at the structural relations of the dual construct representation of anxiety and depression with NA, PA and PH in each of the four groups separately, it became evident that the PH and PA tripartite dimensions could not account for the unique aspects of anxiety and depression respectively. Moreover, PH rather than NA was found to be common for anxiety and depression.     

The Application of Behavior Change Theory to Family-Based Services: Improving Parent Empowerment in Children’s Mental Health

We describe the development of a parent empowerment program (PEP) using a community-based participatory research approach. In collaboration with a group of dedicated family advocates working with the Mental Health Association of New York City and state policy makers, academic researchers took an iterative approach to crafting and refining PEP to better prepare family advocates to help bridge the gaps in service access among children with emotional and behavioral problems. Despite the growth of family-led, family support programs nationally, research that demonstrates the positive benefits of such programs is scarce in the children’s mental health literature. The PEP model is based on research data about barriers families face in mental health service utilization (e.g., stigma, perceptions of providers, attitudes towards mental illness, service availability, etc.). PEP is premised on (a) the concept of empowerment as a process, (b) the need to engage parents in becoming active agents of change, and (c) the application of an integrated framework to empower parents, called the Parents as Agents of Change model. Our paper focuses on describing the application of a Unified Theory of Behavior Change as a theoretical framework to help activate parents as change agents in meeting their children’s mental health needs. Based on an integrated model of grassroots driven Principles of Parent Support and research-based Unified Theory of Behavior Change, PEP’s Parents as Agents of Change model provides a conceptual framework for testing the effectiveness of family support services in children’s mental health, a much-needed area for future research.
