Competing for Reality

In this article, we will apply aspects of Rychlak's philosophy of science to some of the most important issues in psychology today (issues of brain versus behavior, genetic destiny, the nature of scientific investigation, ecopsychology, and artificial intelligence). In our discussion of these issues, we attempt to show the ways that an appreciation of Rychlak's views can help conceptualize the bases of the disagreements in the field as well as explain why so many psychologists tend to “talk past” as opposed to “talk to” one another. We believe that a greater appreciation of Rychlak's major theses could allow psychologists to respect the work of others instead of trying to assert politically their favorite truth claims.     

Modulation sensitivity in the perceptual organization of speech

In a spoken utterance, a talker expresses linguistic constituents in serial order. A listener resolves these linguistic properties in the rapidly fading auditory sample. Classic measures agree that auditory integration occurs at a fine temporal grain. In contrast, recent studies have proposed that sensory integration of speech occurs at a coarser grain, approximate to the syllable, on the basis of indirect and relatively insensitive perceptual measures. Evidence from cognitive neuroscience and behavioral primatology has also been adduced to support the claim of sensory integration at the pace of syllables. In the present investigation, we used direct performance measures of integration, applying an acoustic technique to isolate the contribution of short-term acoustic properties to the assay of modulation sensitivity. In corroborating the classic finding of a fine temporal grain of integration, these functional measures can inform theory and speculation in accounts of speech perception.     

Blood flow velocity changes in anterior cerebral arteries during cognitive tasks performance

Objective

Transcranial Doppler sonography (TCD) enables monitoring of blood flow velocities (BFVs) in basal cerebral arteries during different cognitive tasks performance with great temporal resolution. So far, BFVs changes during mental activity were monitored primarily in middle cerebral arteries (MCAs) and little is known about these changes in anterior cerebral arteries (ACAs).

Aim

To determine the effect of different cognitive tasks performance on BFV changes and hemispheric dominance in ACAs and to assess the most suitable activation test for monitoring of BFV changes in ACAs.

Methods

Fourteen right-handed, healthy subjects aged 20–26 were included in the study. BFVs in both ACAs were recorded simultaneously during performance of cognitive tasks designed to activate frontal lobes: phonemic verbal fluency test (pVFT), Stroop tests and Trail Making Tests (TMTs).

Results

A statistically significant BFV increase was recorded in both ACAs during performance of all cognitive tasks. Statistically significant right ACA dominance was found during performance of pVFT and TMTB. The most significant BFV increase was obtained during performance of TMTB.

Conclusion

Our result addressed cognitive tests with great activation potential for monitoring of ACAs that might be used in distinguishing of healthy individuals and patients with neurovascular or neurodegenerative diseases.     

Prosodic structure and syntactic acquisition: the case of the head‐direction parameter

We propose that infants may learn about the relative order of heads and complements in their language before they know many words, on the basis of prosodic information (relative prominence within phonological phrases). We present experimental evidence that 6–12‐week‐old infants can discriminate two languages that differ in their head direction and its prosodic correlate, but have otherwise similar phonological properties (i.e. French and Turkish). This result supports the hypothesis that infants may use this kind of prosodic information to bootstrap their acquisition of word order.     

Values and Voting

We examined relations of the 10 types of values in Schwartz's (1992) theory of voting. Hypotheses were generated by relating the core motivations of each value type to the ideological messages conveyed by party policies and symbols. Eight parties that ran in the 1988 Israeli elections were arrayed by judges on three ideological dimensions: classical liberalism, economic egalitarianism, state and religion. Discriminant analyses yielded a function whose coefficients for value types corresponded to hypotheses for the state and religion dimension and ordered party supporters on this dimension. After dropping religious parties, another value-based function ordered party supporters on the classical liberalism dimension, as predicted. Both functions significantly improved the party classification of voters in a representative national sample (N=769). Economic egalitarianism, a nonsalient dimension in Israeli politics, was unrelated to values. Results suggest that all types of values may be politically relevant depending on context.     

Self-Criticism and Depressive Symptoms Mediate the Relationship Between Emotional Experiences With Family and Peers and Self-Injury in Adolescence

Although the relationship between negative childhood experiences, peer victimization, depressive symptoms, and Non-Suicidal Self-Injury (NSSI) is widely recognized, the mechanisms involved are not fully understood, especially among adolescents. This study aims to test the mediating role of both self-criticism and depressive symptoms in the relationship between memories of negative or positive experiences, current peer victimization, and NSSI. The sample consists 854 Portuguese adolescents, 451 female and 403 male, with ages between 12 and 18 years (M = 14.89; SD = 1.79), from middle and secondary schools. Participants answered self-report measures. Results from path analysis showed that memories of negative experiences, the absence of positive memories with family in childhood and peer victimization indirectly impact on NSSI through self-criticism and depressive symptoms. In addition, these stressful experiences led to depressive symptoms through self-criticism. Lastly, the most severe form of self-criticism indirectly impacts on NSSI through depressive symptoms, even though it also has a strong direct effect. It suggests that negative experiences with parents and peer victimization, as well as the absence of positive memories with family, have a negative impact on NSSI when these experiences are linked with a sense of self-hatred and depressive symptoms.     

The Indirect Effect of Early Experiences on Deliberate Self-Harm in Adolescence: Mediation by Negative Emotional States and Moderation by Daily Peer Hassles

The present study examines whether early experiences of threat, subordination and devaluation with family influence adolescents’ negative emotional states and subsequently deliberate self-harm; and if this effect is conditioned by daily peer hassles. The sample consisted of 441 adolescents (57.6 % female) with ages between 13 and 18 years old from middle and high schools. Participants completed self-report instruments measuring early memories of threat, subordination and devaluation, daily peer hassles, negative affect and deliberate self-harm behaviors. Results from conditional process analysis showed that adolescents who feel devalued and experience threat and submission within family tend to endorse high levels of negative affect, which in turn accounts for increased endorsements on deliberate self-harm. Moreover, the impact of negative affect on deliberate self-harm is amplified by the presence of moderate and high levels of daily peer hassles. This study suggests the relevance of assessing and intervening on type of emotional memories (i.e., threat, subordination and devaluation), daily disruptions with peers and negative emotional states with adolescents who self-injure. These findings may be useful in the development of preventive and intervention programs for reducing deliberate self-harm in adolescence.     

A Place for Every Event and Every Event in Its Place: Memory for Locations and Activities by 4-Year-Old Children

Episodic memories are of specific events and experiences associated with particular times and places. Whereas memory for the temporal aspects of past events has been a focus of research attention, memory for the location in which events were experienced has been less fully investigated. The limited developmental research suggests that preschool-age children, in particular, may have difficulty remembering the location in which they experienced specific events. In 2 experiments, 4-year-old children engaged in 4 unique activities in 4 unique locations in and around a laboratory suite. In Experiment 1, the children had high levels of recall of the activities, the locations, and the conjunctions of activities and locations, implying that they had formed memory representations that featured activities bound in locations. In Experiment 2, we tested whether 1 element of the bound representation—the location of an activity—served as a reliable cue to recall of the other element—the activity itself. The test was positive, providing further evidence that 4-year-old children form mnemonic conjunctions of activities and locations. The results imply that important elements of episodic memory are available to young children.     

Whose Side Are You On? Exploring the Role of Perspective Taking on Third-Party’s Reactions to Workplace Deviance

We introduce perspective taking as an antecedent of third-party reactions to different forms of workplace deviance. Varying the perspective taken by third-parties, the target and the type of workplace deviance, we show that third-parties who take the perpetrator’s perspective perceive the incident as less of a moral violation, make less internal, and more external attributions for the perpetrator’s behavior, which in turn reduces endorsement of punishment. Findings were consistent across four studies, and the mediating mechanisms supported by the instrumental variable method and the concurrent double randomization design.     

Collateral Reports and Cross-Informant Agreement about Adult Psychopathology in 14 Societies

To advance international mental health assessment, instruments that have been internationally validated are needed. To this end, we analyzed ratings from 14 societies on the Adult Behavior Checklist (ABCL), a collateral-report form parallel to the Adult Self-Report (ASR; Achenbach and Rescorla 2003) for ages 18 to 59. Both the ABCL and the ASR assess problems, personal strengths, and adaptive functioning. For a sample of 8322 see note below collaterals, we found strong consistency across societies regarding which ABCL problem items tended to obtain relatively low, medium, or high ratings. Most societal effect sizes (ESs) for problem scale scores were small to medium (< 13.9 %), but the ES for the ABCL Personal Strengths scale was 25 %. For most of the same participants (N = 8,302), we analyzed cross-informant agreement between self-reports on the ASR and collateral reports on the ABCL. Cross-informant correlations for problem scale scores averaged .47, with considerable societal variation. Problem score means were higher on the ASR than the ABCL in every society, but the size of the difference varied across societies. Mean item ratings on the ABCL and ASR were highly correlated within every society (mean r = .92), but within-dyad item rating agreement varied widely in every society (mean r = .39). In all societies, non-corroboration of self-reported deviance and of collateral-reported deviance was common. Overall findings indicated considerable similarity but also some important differences in collateral-reported problems and adaptive functioning across 14 societies.
