Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.

No anticipation–no action: the role of anticipation in action and perception

This paper reviews psychophysical evidence for the existence and the nature of two types of anticipation in goal-oriented action. The first one relates to attained changes of the perceptual world, thus to action goals. These anticipations determine appropriate motor output. We argue that goal codes do not only serve as a reference unit, against which currently produced behavioral effects are compared. Rather voluntary actions appear to be planned literally in terms of intended behavioral effects. The second type of anticipation relates to the environmental conditions that have to be met to bring an intended effect into being. These anticipations serve to trigger selected actions, when appropriate execution conditions are encountered. Altogether, the behavioral evidence portrays a remarkable automaticity of goal-oriented action. Once a goal exists (wherever it might come from), corresponding efferent output is generated and executed under appropriate conditions.     

Two meanings of "if"? Individual differences in the interpretation of conditionals

This work investigates the nature of two distinct response patterns in a probabilistic truth table evaluation task, in which people estimate the probability of a conditional on the basis of frequencies of the truth table cases. The conditional-probability pattern reflects an interpretation of conditionals as expressing a conditional probability. The conjunctive pattern suggests that some people treat conditionals as conjunctions, in line with a prediction of the mental-model theory. Experiments 1 and 2 rule out two alternative explanations of the conjunctive pattern. It does not arise from people believing that at least one case matching the conjunction of antecedent and consequent must exist for a conditional to be true, and it does not arise from people adding the converse to the given conditional. Experiment 3 establishes that people's response patterns in the probabilistic truth table task are very consistent across different conditionals, and that the two response patterns generalize to conditionals with negated antecedents and consequents. Individual differences in rating the probability of a conditional were loosely correlated with corresponding response patterns in a classical truth table evaluation task, but there was little association with people's evaluation of deductive inferences from conditionals as premises. A theoretical framework is proposed that integrates elements from the conditional-probability view with the theory of mental models.     

The Simon effect for vertical S–R relations: changing the mechanism by randomly varying the S–R mapping rule?

Recent findings indicate that the shape of the effect function of the Simon effect--derived by analysing the response time distribution for corresponding and non-corresponding trials--differs depending on the task. Specifically, decreasing effect functions have been reported for horizontal and stable rather increasing effect functions have been obtained for vertical stimulus-response (S-R) relations. Furthermore, it has been assumed that these differences reflect distinct mechanisms underlying the Simon effect. However, in two studies decreasing effect functions were reported for the vertical dimension. In order to investigate these contradictory findings four experiments were conducted. Since both studies--in which a decreasing effect function was obtained--used a modified version of the Simon task, that is, randomly varying S-R mapping rules, the Simon effect for fixed and random S-R mapping rules was investigated using vertical (Experiments 1, 2, and 4) and horizontal (Experiment 3) S-R relations. The results indicate that randomly varying S-R mapping rules affect the shape of the effect function for vertical but not for horizontal S-R relations. It was concluded that these findings indicate that the alternation of S-R mapping rules changes the information processing for the vertical dimension in a way, that the same mechanism as for horizontal S-R relations occurs.     

The perceived credibility of older adults as witnesses and its relation to ageism

In experiment 1, 267 undergraduates read a case summary and witness statement. Sex and age of the witness (49, 69, 79 or 89 years) were varied. Participants rated the witness's perceived convincingness, confidence, quality of observation, accuracy, honesty, competence, memory, suggestibility, and cognitive functioning. As well as an age effect for honesty, age by sex interactions were observed for several characteristics, particularly for comparisons of the 79-year-olds versus the 49-year-olds, and 89-year-olds versus the 49-year-olds. In experiment 2, 94 undergraduates read the same testimony given by a 79-year-old male or female witness, and completed the Fraboni Scale of Ageism and the Aging Semantic Differential. Participants who evidenced stronger aging stereotypes on these measures rated the witness less favorably than did participants who were less prejudiced. This experiment is the first to show a link between perceived credibility of older adults and ageist attitudes. Practical applications regarding how older witnesses are viewed by jurors, and the criminal justice system more generally, are discussed.     

Who Turns Green with Envy? Conceptual and Empirical Perspectives on Dispositional Envy

Previous research has conceptualized dispositional envy as a general construct that does not vary across comparison domains. In five studies (N = 1393), we examine dispositional envy as a domain‐specific construct. In Study 1, we present the development of a domain‐specific measure of dispositional envy. Across samples from different populations and two countries (Studies 2 and 3), the measure is shown to have good reliability, construct validity and stability over three months, highlighting the trait‐like character of the construct. State levels of envy were also examined in the academic domain (Study 4) and in dyadic interactions between unacquainted participants (Study 5). Results show a Person × Situation Interaction effect (i.e. Dispositional Envy × Situation) on experiences of envy. By placing domain‐specific dispositional envy into a network of similar and dissimilar constructs, the current findings serve as a foundation for drawing conclusions about the nature of dispositional envy.

Stability and Change in Domain‐specific Self‐esteem and Global Self‐esteem

A notable uptick of interest in the stability of self‐esteem has been observed over the past few years. Most researchers, however, have focused on unidimensional rather than multidimensional conceptualizations of self‐esteem. The paucity of empirical research is surprising given conflicting theoretical perspectives on the stability of self‐esteem. The goal of the present study was to thoroughly disentangle different conceptualizations of self‐esteem and test opposing classical theories on (i) the stability and (ii) the direction of mutual influence of these different forms of self‐esteem. We analysed two‐year longitudinal data from participants (N = 644 at T1, N = 241 at T2) with an average age of 47.0 years (SD = 12.4). Analyses using a latent variable approach revealed that the domains of self‐esteem were relatively stable in terms of rank order and mean levels. In fact, the size of the stability coefficients was comparable to that of other trait measures that have been reported in the literature and paralleled the stability observed for global self‐esteem. Results did not provide support for either top‐down or bottom‐up effects between domain‐specific and global self‐esteem. These findings have important theoretical and practical implications regarding the stability and development of self‐esteem in adulthood and advance the understanding of self‐esteem in personality theory. © 2018 European Association of Personality Psychology     

Psychological stigma costs as barriers to healthcare use in former soldiers of the German Armed Forces: A qualitative analysis

Individuals decide to use healthcare when the expected benefits outweigh the perceived costs. One of these cost factors in this decision can be stigma. So far, it has not been researched how former soldiers of the German Armed Forces with a service-induced mental illness perceive stigma and how it influences their healthcare use. As stigma is shaped by the socio-cultural context, the setting of the potential healthcare use must be considered. Narrative interviews were conducted with 33 former soldiers with mental health problems. The data were analyzed using a thematic analysis approach, in which codes were formed and emerging themes were systemized. The relationship between stigma and healthcare use was analyzed. Occupational discrimination and social exclusion were experienced in both in the military and civilian context, but stigma functioned differently in each context. In the military context, former soldiers’ self-stigma of mentally ill individuals being weak was in stark contrast to their internalized military standards. This contrast let them avoid disclosure and subsequent healthcare use. In civilian context, the participants perceived 2 different stigma costs: mental illness stigma and former soldier stigma (i.e., stigmatization because of their military past). Both were perceived as barriers to healthcare use. A model, illustrating these different stigma costs in the different contexts, was developed. Further research on the link between stigma and healthcare use of this group is urgently needed.     

Gender of the expresser moderates the effect of emotional faces on the startle reflex

It has been suggested that the impact of emotional expressions on the startle reflex is influenced by the intention communicated by the expression (e.g., the intention to attack). However, we propose that the meaning of an emotional expression is not only based on the intention, but is also influenced by characteristics of the expresser such as gender: since men are typically seen as more dominant than women, anger expressed by men should be perceived as particularly threatening, thus amplifying the startle response. We compared the influence of anger, fear and neutral expressions shown by men and women on the startle reaction. Startle reactions were measured using electromyography. As predicted, we found stronger startle reactions after the presentation of anger expressed by men compared to fearful and neutral expressions shown by men. For female expressers, the startle response was not affected by expression type.
