The experience of body dissatisfaction in men

Evidence suggests that the prevalence of body dissatisfaction (BD) is increasing amongst men. However, research has commonly examined the phenomenon in predominantly female groups. In view of this, the current study used a qualitative methodology to explore the experience of BD in men. Semi-structured interviews were conducted with 14 men. The data were analysed using Interpretative Phenomenological Analysis. Analysis yielded themes across four domains (societal, interpersonal, intrapersonal, and social presentation). Whilst participants exhibited a range of appearance concerns, there was commonality in the processes by which these were experienced and managed. These generic issues are the focus of the themes, and could usefully be incorporated into a new assessment tool. Findings are considered in relation to existing (cognitive behavioural, self-discrepancy, and sociocultural) theories, and implications for clinical practice and future research are discussed.     

Anxiety-linked expectancy bias across the adult lifespan

Anxiety is characterised by a negative expectancy bias, such that anxious individuals report negatively distorted expectations about the future. Contrary to anxiety, ageing is characterised by a positivity effect, such that ageing is associated with a tendency to attend to and remember positive information, relative to negative information. The current study integrates these literatures to examine anxiety- and age-linked biases when thinking about the future. Participants (N=1,109) completed a procedure that involved reading valenced scenarios (positive, negative, or ambiguous) and then rating the likelihood of future valenced events occurring. Results suggest that ageing and anxiety have independent and opposing effects. Heightened anxiety was associated with a reduced expectancy for positive events, regardless of the scenarios’ current emotional valence, whereas increased age was associated with an inflated expectancy for positive events, which was strongest when individuals were processing socially relevant or negative scenarios.     

Macaque monkeys discriminate pitch relationships

This study demonstrates that non-human primates can categorize the direction of the pitch change of tones in a sequence. Two Macaca fascicularis were trained in a positive-reinforcement behavioral paradigm in which they listened to sequences of a variable number of different acoustic items. The training of discriminating pitch direction was divided into three phases with increasing task complexity. In the first two phases, subjects learned to employ a same/different rule. In phase 1, they discriminated acoustic items of different sound quality. Subjects had to respond when there was a change from repeating noise bursts to repeating click trains or vice versa. In phase II, acoustic items differed along one physical dimension only. Subjects had to respond to a change of the frequency of a repeating series of pure tones. In phase III, sequences consisted of three series of repeating tones of different frequency. Subjects were required to respond when the frequency of the tones changed in a downward direction and to refrain from responding when the frequency remained constant or increased. After several ten thousand trials, subjects categorized pitch direction well above chance level. The discrimination was performed over a 4.5-octave range of frequencies and was largely independent of the temporal and ordinal position of the downward pitch direction within the sequence. These results demonstrate that monkeys can recognize pitch relationships and thus that monkeys have the concept of ordinal relations between acoustic items.
