Sensitivity to tonality across the pitch range

Striking changes in sensitivity to tonality across the pitch range are reported. Participants were presented a key-defining context (do-mi-do-sol) followed by one of the 12 chromatic tones of the octave, and rated the goodness of fit of the probe tone to the context. The set of ratings, called the probe-tone profile, was compared to an established standardised profile for the Western tonal hierarchy. The presentation of context and probe tones at low and high pitch registers resulted in significantly reduced sensitivity to tonality. Sensitivity was especially poor for presentations in the lowest octaves where inharmonicity levels were substantially above the threshold for detection. We propose that sensitivity to tonality may be influenced by pitch salience (or a co-varying factor such as exposure to pitch distributional information) as well as suprathreshold inharmonicity.     

Gender Role Beliefs and Attitudes toward Lesbians and Gay Men in Chile and the U.S.

We compared the relationship between gender role beliefs and antigay prejudice in Chile and the United States. Participants were Chilean and American university students. In Study 1, Chileans were more prejudiced than Americans, and men were more prejudiced than women. In Study 2, gender role beliefs mediated cultural and sex differences in prejudice. Chileans held more traditional gender role beliefs and were more antigay than Americans. Men were more prejudiced than women, particularly in their attitudes toward gay men. Further, sex differences in attitudes toward lesbians and gay men were completely mediated by gender role beliefs. Nationality differences in attitudes toward lesbians were completely mediated, and nationality differences in attitudes toward gay men were partially mediated, by gender role beliefs.     

Don’t hate me because I’m beautiful: Self-enhancing biases in threat appraisal

We compare people’s intuitive judgments about how the self and others respond to threat. We propose that people hold a self-enhancing belief in ”threat immunity,” i.e., they see themselves as more secure than other people in the face of threat. In Study 1, people assumed that they threatened others more than others threatened them. In Study 2, people on project teams estimated that both they and their teammates provoked roughly equal levels of threat in others, although they experienced less threat than did other people. Study 3 experimentally manipulated threat perceptions in an interactive context and revealed that when people held self-enhancing threat appraisals, those with whom they interacted experienced lower satisfaction with the outcome and relationship. Finally, Study 4 demonstrated that, as compared to people who affirmed themselves and thus focused on the self, people who affirmed another person displayed lower threat immunity. The self-enhancing nature of these threat appraisals reveals how competition and envy emerge in organizations—or at least, how people imagine they emerge.     

The relation between worrying and concerns: the importance of perceived probability and cost

The relation between worrying and individuals' concerns was examined in a sample of 197 college students. Participants described the five undesirable outcomes that they thought about most often, indicated how likely they thought the outcomes were, and how upset they would be by them. Worry severity was measured using the Penn State Worry Questionnaire. The relation between worry severity and the life domains about which individuals were concerned was quite weak. In contrast, as predicted, greater worry was associated with higher probability and cost estimates. In addition, cost estimates moderated the relation between worry severity and probability estimates. The potential importance of perceived threat for understanding worrying is discussed.     

Exploring the trainees' view of a socio‐political approach within UK clinical psychology

This paper aims to provide preliminary insights into the relationship between clinical psychology and a socio‐political approach known as Critical Community Psychology (CCP). Methodologically, it uses statements about CCP as stimulus material, and utilizes both quantitative and qualitative exploratory techniques, to survey the opinions of 354 UK trainee clinical psychologists. Participants' ratings of the stimulus material and their qualitative comments reveal many positive endorsements of the socio‐political approach. However, themes from the qualitative data raise questions about how socio‐political ideas can be incorporated into clinical practice and highlight uncertainty over the relationship between clinical psychology and politics.

Eye-blink conditioning is associated with changes in synaptic ultrastructure in the rabbit interpositus nuclei

Eye-blink conditioning involves the pairing of a conditioned stimulus (usually a tone) to an unconditioned stimulus (air puff), and it is well established that an intact cerebellum and interpositus nucleus, in particular, are required for this form of classical conditioning. Changes in synaptic number or structure have long been proposed as a mechanism that may underlie learning and memory, but localizing these changes has been difficult. Thus, the current experiment took advantage of the large amount of research conducted on the neural circuitry that supports eye-blink conditioning by examining synaptic changes in the rabbit interpositus nucleus. Synaptic quantifications included total number of synapses per neuron, numbers of excitatory versus inhibitory synapses, synaptic curvature, synaptic perforations, and the maximum length of the synapses. No overall changes in synaptic number, shape, or perforations were observed. There was, however, a significant increase in the length of excitatory synapses in the conditioned animals. This increase in synaptic length was particularly evident in the concave-shaped synapses. These results, together with previous findings, begin to describe a sequence of synaptic change in the interpositus nuclei following eye-blink conditioning that would appear to begin with structural change and end with an increase in synaptic number.     

The nature of skilled adult reading varies with type of instruction in childhood

Does the type of reading instruction experienced during the initial years at school have any continuing effect on the ways in which adults read words? The question has arisen in current discussions about computational models of mature word-reading processes. We tested predicted continuing effects by comparing matched samples of skilled adult readers of English who had received explicit phonics instruction in childhood and those who had not. In responding to nonwords that can receive alternative legitimate pronunciations, those adults having childhood phonics instruction used more regular grapheme-phoneme correspondences that were context free and used fewer vocabulary-based contextually dependent correspondences than did adults who had no phonics instruction. These differences in regularization of naming responses also extended to some low-frequency words. This apparent cognitive footprint of childhood phonics instruction is a phenomenon requiring consideration when researchers attempt to model adult word reading and when they select participants to test the models.     

Making Sense of Sense-Making: Reflections on Enactive and Extended Mind Theories

This paper explores some of the differences between the enactive approach in cognitive science and the extended mind thesis. We review the key enactive concepts of autonomy and sense-making. We then focus on the following issues: (1) the debate between internalism and externalism about cognitive processes; (2) the relation between cognition and emotion; (3) the status of the body; and (4) the difference between ‘incorporation’ and mere ‘extension’ in the body-mind-environment relation.

Perception of exertion and attention allocation as a function of visual and auditory conditions

AimThe aim of the present study was to test the role of auditory (e.g., music) and visual sensory modalities on perceived levels of exertion and attention processes across a 30% dynamometer-squeezing task. The study explored the dynamics embedded within the automated nature of the association–dissociation shift process.MethodSixty young adults (33 male and 27 female; M_age = 22.21 yrs, SD = 3.49) were recruited to perform a handgrip-squeezing task. They were randomly assigned to 4 groups of 15 participants. After establishing the maximal squeezing value they performed 30% max squeezing-task under one of four assigned condition: full vision and preferred music, full vision and no music, blindfolded and preferred music, and blindfolded and no music until volitional fatigue. Rate of perceived exertion and attention strategies were administered at 30 s intervals.ResultsA set of Repeated Measures ANOVAs indicated an additive effect of visual and auditory cues on the perception of exertion, and the dynamic pattern of attention shift. Participants who were given both forms of sensory information remained in a dissociative strategy for a significantly longer duration than participants in all other conditions.ConclusionsSeveral sensory modalities are required to affect perceived exertion and attention allocation while engaging in demanding workload. External stimuli may serve as mediating agents in diverting attention away from internal and painful stimuli. This distraction may likely contribute to the pleasantness of the exercise experience, ultimately leading to increased exercise participation and reduced dropout rates.
