Interfering with inferential, but not associative, processes underlying spontaneous trait inference

Three studies explore mental processes underlying spontaneous trait inferences about self-informants and the spontaneous trait transference characterizing third-party informants. Process differences are suggested in that instructions prompting a nontrait inference (truth or lie?) reduce self-informant trait-savings effects and lower self-informant trait judgments. For third-party informants, such instructions have no effect on these outcome variables. Results of a third study are inconsistent with cognitive load as an explanation for these effects. Taken together, these results indicate that inferences, and not merely associations, spontaneously form when processing information about self-informants. The results also show that the inferences and judgments that occur in spontaneous trait transference are not caused by the misidentification of third-party informants as self-informants.     

Interpretive flexibility: why doesn't insight incite controversy in mental health law?

This research investigates how the term "insight" was employed in 25 decisions from mental health review proceedings in Victoria, Australia. The application of insight appears problematic in these decisions. First, there is little clarification of its meaning. Second, the logic applied when insight is related to compliance is often unclear. Third, there are frequent allusions to an implicit and undefined scale of insight, offering the appearance of objectivity. We have analysed insight as an 'interpretive resource', focusing on its various functions in the complex social context of commitment hearings and with a view to its therapeutic jurisprudence implications. The variable application of insight-its interpretive flexibility-appears useful in addressing complex problems faced by review boards. Hence, a key function of insight is to bridge between legal and clinical discourses. Insight is also a convenient means to avoid complicated debates regarding the person's credibility. By analysing insight in Victoria, we hope to contribute to better theoretical understanding of decision-making patterns in mental health law in general.     

The world of emotions is not two-dimensional

For more than half a century, emotion researchers have attempted to establish the dimensional space that most economically accounts for similarities and differences in emotional experience. Today, many researchers focus exclusively on two-dimensional models involving valence and arousal. Adopting a theoretically based approach, we show for three languages that four dimensions are needed to satisfactorily represent similarities and differences in the meaning of emotion words. In order of importance, these dimensions are evaluation-pleasantness, potency-control, activation-arousal, and unpredictability. They were identified on the basis of the applicability of 144 features representing the six components of emotions: (a) appraisals of events, (b) psychophysiological changes, (c) motor expressions, (d) action tendencies, (e) subjective experiences, and (f) emotion regulation.     

Characterization of music-evoked autobiographical memories

Despite music's prominence in Western society and its importance to individuals in their daily lives, very little is known about the memories and emotions that are often evoked when hearing a piece of music from one's past. We examined the content of music-evoked autobiographical memories (MEAMs) using a novel approach for selecting stimuli from a large corpus of popular music, in both laboratory and online settings. A set of questionnaires probed the cognitive and affective properties of the evoked memories. On average, 30% of the song presentations evoked autobiographical memories, and the majority of songs also evoked various emotions, primarily positive, that were felt strongly. The third most common emotion was nostalgia. Analyses of written memory reports found both general and specific levels of autobiographical knowledge to be represented, and several social and situational contexts for memory formation were common across many memories. The findings indicate that excerpts of popular music serve as potent stimuli for studying the structure of autobiographical memories.     

Top-down influences make saccades deviate away: the case of endogenous cues

We tested a recent hypothesis suggesting that the eye deviates away from a location when top-down preparation can influence target selection. Participants had to make an eye movement to a peripheral target. Before the upcoming target, a central cue indicated the likely target location. Results show that when the target was presented at a location different from that indicated by the cue, eye movements to the target deviated away from the cued location. Because central cues are under top-down control, the present results are in line with a determining role of top-down preparation on saccade direction. These results contrast with the findings reported in a similar paradigm executed with hand movements, in which the movements were mostly initiated in the direction of the cued location. Therefore, we conclude that inhibitory effects typically observed when executing eye movements may not be observed when executing hand movements in similar conditions.     

Digit ratio (2D:4D) in twins: heritability estimates and evidence for a masculinized trait expression in women from opposite-sex pairs

The second-to-fourth digit ratio (2D:4D) is sexually dimorphic in humans, such that men on average have a lower 2D:4D than women. This somatic trait has been proposed as a biomarker for the organizational (permanent) effects of prenatal testosterone on the brain and behavior. Over the past few years, an accumulating research program has shown 2D:4D to be related to a multitude of sex-dependent, hormonally influenced psychological and behavioral traits. The present study investigated the 2D:4D ratio of 44 men and 70 women from 36 identical and 21 fraternal twin pairs. Both basic and advanced approaches for estimating heritability concordantly suggested that the trait is substantially heritable. The best-fitting structural equation model indicated that the contributions to individual differences in 2D:4D are 81% additively genetic, 19% nonshared environmental, and 0% shared environmental. Supplemental analyses showed that, consistent with a prediction from sex-hormone transfer theory, women from opposite-sex fraternal twin pairs had significantly lower (more male-typical) 2D:4D than women from same-sex fraternal twin pairs. Directions for research are discussed, such as investigating possible influences of the sex chromosomes on the expression of 2D:4D. Further family studies will be needed to test whether the transmission mode of 2D:4D is consistent with X-linked or Y-linked inheritance. The study of sex chromosome aberrations should indicate whether the presence of additional X or Y chromosomes is associated with 2D:4D levels.     

The Depressive Experiences Questionnaire: on using a student-based scoring program for a clinical sample

In both clinical and nonclinical samples, the Depressive Experiences Questionnaire is scored with a program that computes factor scores by using means, standard deviations, and item-loadings of a student sample. The underlying assumption of the use of this program in clinical samples is that factor scores computed on the basis of the student factor solution are similar to factor scores computed on the basis of a clinical factor solution. Consequently, both series of scores should lead up to the same conclusions when studying associations with theoretically related variables. This assumption has not been tested although the questionnaire has been used in research for almost 30 years. In the present paper an alternative scoring program was constructed, based on the factor solution of a clinical sample (N = 400) to assess whether scores of this clinical scoring program are associated in the same way with different types of depressive symptoms and interpersonal problems as the scores of the original (student-based) program. Analysis gave results inconsistent with the assumption and did not support the use of the student-based scoring program in the clinical sample. Further, results suggest that standards for assessing factorial similarity used in confirmatory factor analysis might be too lenient.     

Visual attention: of features and transparent surfaces

A recent report by Wannig et al. demonstrated the effects of selectively attending to individual surfaces in transparent motion patterns on neurons in the middle temporal area of awake, behaving monkeys. The study illustrates a highly adaptive and flexible attentional modulation of sensory responses.     

Hearing facial identities

While audiovisual integration is well known in speech perception, faces and speech are also informative with respect to speaker recognition. To date, audiovisual integration in the recognition of familiar people has never been demonstrated. Here we show systematic benefits and costs for the recognition of familiar voices when these are combined with time-synchronized articulating faces, of corresponding or noncorresponding speaker identity, respectively. While these effects were strong for familiar voices, they were smaller or nonsignificant for unfamiliar voices, suggesting that the effects depend on the previous creation of a multimodal representation of a person's identity. Moreover, the effects were reduced or eliminated when voices were combined with the same faces presented as static pictures, demonstrating that the effects do not simply reflect the use of facial identity as a “cue” for voice recognition. This is the first direct evidence for audiovisual integration in person recognition.
