Psychoacoustic cues to emotion in speech prosody and music

There is strong evidence of shared acoustic profiles common to the expression of emotions in music and speech, yet relatively limited understanding of the specific psychoacoustic features involved. This study combined a controlled experiment and computational modelling to investigate the perceptual codes associated with the expression of emotion in the acoustic domain. The empirical stage of the study provided continuous human ratings of emotions perceived in excerpts of film music and natural speech samples. The computational stage created a computer model that retrieves the relevant information from the acoustic stimuli and makes predictions about the emotional expressiveness of speech and music close to the responses of human subjects. We show that a significant part of the listeners’ second-by-second reported emotions to music and speech prosody can be predicted from a set of seven psychoacoustic features: loudness, tempo/speech rate, melody/prosody contour, spectral centroid, spectral flux, sharpness, and roughness. The implications of these results are discussed in the context of cross-modal similarities in the communication of emotion in the acoustic domain.     

Reliability and plasticity of response inhibition and interference control

This study investigated the internal reliability, temporal stability and plasticity of commonly used measures of inhibition-related functions. Stop-signal, go/no-go, antisaccade, Simon, Eriksen flanker, Stroop and Continuous Performance tasks were administered twice to 23 healthy participants over a period of approximately 11 weeks in order to assess test–retest correlations, internal consistency (Cronbach’s alpha), and systematic between as well as within session performance changes. Most of the inhibition-related measures showed good test–retest reliabilities and internal consistencies, with the exception of the stop-signal reaction time measure, which showed poor reliability. Generally no systematic performance changes were observed across the two assessments with the exception of four variables of the Eriksen flanker, Simon and Stroop task which showed reduced variability of reaction time and an improvement in the response time for incongruent trials at second assessment. Predominantly stable performance within one test session was shown for most measures. Overall, these results are informative for studies with designs requiring temporally stable parameters e.g. genetic or longitudinal treatment studies.     

The Mechanisms of Space‐Time Association: Comparing Motor and Perceptual Contributions in Time Reproduction

The spatial‐temporal association indicates that time is represented spatially along a left‐to‐right line. It is unclear whether the spatial‐temporal association is mainly related to a perceptual or a motor component. In addition, the spatial‐temporal association is not consistently found using a time reproduction task. Our rationale for this finding is that, classically, a non‐lateralized button for performing the task has been used. Using two lateralized response buttons, the aim of the study was to find a spatial‐temporal association in a time reproduction task. To account for the perceptual component, reference and target stimuli were presented in different spaces through four experiments. In all experiments, a Spatial‐Temporal Association of Response Codes (STEARC) effect was found and this effect was not modulated by the spatial position of both reference and target stimuli. The results suggested that the spatial‐temporal association was mainly derived from the spatial information provided by response buttons, reflecting a motor but not visuospatial influence.     

The impact of cognitive control on children’s goal monitoring in a time-based prospective memory task

The present study investigated whether developmental changes in cognitive control may underlie improvements of time-based prospective memory. Five-, 7-, 9-, and 11-year-olds (N = 166) completed a driving simulation task (ongoing task) in which they had to refuel their vehicle at specific points in time (PM task). The availability of cognitive control resources was experimentally manipulated by imposing a secondary task that required divided attention. Children completed the driving simulation task both in a full-attention condition and a divided-attention condition where they had to carry out a secondary task. Results revealed that older children performed better than younger children on the ongoing task and PM task. Children performed worse on the ongoing and PM tasks in the divided-attention condition compared to the full-attention condition. With respect to time monitoring in the final interval prior to the PM target, divided attention interacted with age such that older children’s time monitoring was more negatively affected by the secondary task compared to younger children. Results are discussed in terms of developmental shifts from reactive to proactive monitoring strategies.     

Inequity aversion in human adults: testing behavioural criteria from comparative cognition

Inequity aversion refers to an attempt to reduce a perceived discrepancy between one’s own input and output ratio (i.e. ratio between work invested and rewards obtained) and that of others. It has been proposed that inequity aversion might also play a role in the decision-making process of other animals. One issue, however, is that while studies in comparative cognition define clear behavioural criteria for an inequity aversion effect in animals, studies conducted on humans rely on an implicit definition of the concept involving assumptions for which there is yet no experimental evidence. In particular, the basis of inequity aversion is assumed to be a social comparison process that is further motivated by fairness concerns. Based on the studies on non-human animals, we tested whether inequity aversion in adult humans will satisfy the behavioural criteria for these assumptions. Although humans showed a decrease in working for a lower-value reward when working alone (non-social effect), this effect was enhanced when a partner was present (social effect) suggesting that their inequity aversion might be based on a social comparison process. Additionally, our tests ruled out the possibility that selfish motives underlie the subjects’ decisions, which raises the possibility that fairness concerns might have been the primary motive. Our results thus show that human behaviour satisfies two criteria imposed by the definition of inequity aversion. A similar pattern is shown in other species, suggesting that the same or similar processes might influence economic decision-making in both humans and non-human animals.     

Rebirth,Community and Communal Karma in Shan Communities in Northwestern Thailand

In the Shan community of Thongmakhsan, northwestern Thailand, where I have done most of my ethnographic research, children are often identified as so-and-so who was reborn. These identifications are based on appearance, personal proclivities, and dreams around the time the child was born. I begin with the account of Ay Phit and his rebirth since it is this story which piqued my interest in rebirth. I then provide some background information on Shan in Maehongson Province. With this background, I begin the discussion of rebirth by examining local ideas about attachment and its consequences and then go on to discuss the ongoing relationship between the living and the dead, reborn or not, through the transfer of merit. I then describe possible rebirths to argue that rebirth as a human being is the most likely rebirth. In conclusion, I discuss communal karma to raise the question of the relationship between textual analyses and current local practices.     

The good,the bad and the uncertainty: Trainees' perceptions of the personal development group

Background: Views about the purpose and role of personal development groups (PD group) in the counsellor training process are varied. Some argue they enhance self‐awareness, self‐exploration, the ability to be congruent and, ultimately, that they make for better practitioners. Others argue there is no clear evidence for such benefits and that they can actually be damaging to trainees. Aims: This study aimed to explore the beliefs of 25 trainees enrolled on counselling diploma or counselling psychology doctoral courses. It looked in particular at their perceptions of the purpose of PD groups and their expectations regarding support, difficulties and the scope of their participation. Method: Data was collected using open‐ended questions in an anonymous survey and was subjected to a thematic analysis. Results: Trainees appeared to hold mixed – and sometimes conflicting – views about the PD group. For some it was a positive endeavour that facilitated learning about self and clients, and helped in the processes of developing counselling skills and keeping the training group healthy. For others it was a feared space, which could elicit negative emotional experiences, and impact negatively on both learning outside of the PD group and the health of the group itself. Still others were unclear about its purpose. Hope/idealisation (of the process, the facilitator and course tutors) were also evident in the trainees' responses. Implications: Implications of these findings for counselling training are discussed.     

Andrew Robinson. God and the World of Signs: Trinity,Evolution and the Metaphysical Semiotics of C.S. Peirce

ABSTRACT

Christian theologians have considered the significance of life elsewhere in the cosmos since the fifteenth century, but the brevity of these discussions calls for greater theological precision: the notion of multiple incarnations, for example, is often explored without reference to the detail of Christological formulations. Attention to the logical mode in which such work is set out is also fruitful, where the scholastic category of suitability or fittingness holds particular promise. As suitable, God’s actions are free and yet congruent, being consistent with the divine nature, with creaturely natures, and with the ends of God’s dealings with creatures.     

The Relation of Parent and Child Gender to Parental Tolerance of Child Disruptive Behaviors

Parental tolerance has been defined as the degree to which a parent tends to be annoyed by his or her child’s disruptive behavior. The purpose of the current study is to examine the relation of both parent and child gender to parental tolerance of child disruptive behaviors. Participants were 150 parents with 3–6 year-old at-risk children (47.5 % girls) who sought help with parenting of their child’s oppositional defiant behaviors. Tolerance was measured by the difference between parent ratings of intensity on 36 disruptive behaviors and whether each behavior was identified as a problem (resulting in a score of either high, expected, or low tolerance). A 2 (child gender) by 2 (parent gender) analysis of variance was conducted on the tolerance score. A significant interaction between child and parent gender emerged: Mothers were equally tolerant of boys’ and girls’ oppositional defiant behavior but fathers were more tolerant of boys’ than girls’ oppositional behavior. Exploratory analyses suggested that this interaction may be qualified by clinical status of the child. Implications and future directions are discussed.
