Examining auditory kappa effects through manipulating intensity differences between sequential tones

The auditory kappa effect is a tendency to base the perceived duration of an inter-onset interval (IOI) separating two sequentially presented sounds on the degree of relative pitch distance separating them. Previous research has found that the degree of frequency discrepancy between tones extends the subjective duration of the IOI. In Experiment 1, auditory kappa effects for sound intensity were tested using a three-tone, AXB paradigm (where the intensity of tone X was shifted to be closer to either Tone A or B). Tones closer in intensity level were perceived as occurring closer in time, evidence of an auditory-intensity kappa effect. In Experiments 2 and 3, the auditory motion hypothesis was tested by preceding AXB patterns with null intensity and coherent intensity context sequences, respectively. The auditory motion hypothesis predicts that coherent sequences should enhance the perception of motion and increase the strength of kappa effects. In this study, the presence of context sequences reduced kappa effect strength regardless of the properties of the context tones.     

Avoidance of overlearning characterises the spacing effect

The spacing of a fixed amount of study time across multiple sessions usually increases subsequent test performance—a finding known as the spacing effect. In the spacing experiment reported here, subjects completed multiple learning trials, and each included a study phase and a test. Once a subject achieved a perfect test, the remaining learning trials within that session comprised what is known as overlearning. The number of these overlearning trials was reduced when learning trials were spaced across multiple sessions rather than massed in a single session. In addition, the degree to which spacing reduced overlearning predicted the size of the spacing effect, which is consistent with the possibility that spacing increases subsequent recall by reducing the occurrence of overlearning. By this account, overlearning is an inefficient use of study time, and the efficacy of spacing depends at least partly on the degree to which it reduces the occurrence of overlearning.     

The Effects of Elevated Arousal and Mood on Maximal Strength Performance in Athletes

Optimal arousal models contend that high arousal contributes to inhibited athletic performance, whereas there is reversal theory research which indicates that high positive arousal may enhance performance. To test these claims, 22 male and 6 female elite athletes were induced into high arousal telic (goal-directed) and high arousal paratelic (non goal-directed, process focussed) motivational states and tested on a standard hand strength task. Personalized guided imagery techniques and paced breathing were used to change psychological and physiological arousal. Significant increases in strength performance occurred when arousal was high and experienced as pleasant excitement in the paratelic condition (i.e., high positive arousal). Heart rate and other indicators of parasympathetic and sympathetic nervous system activity were not found to mediate between psychological arousal and performance. Where athletic performance requires maximal motor strength over a short period, performance benefits of high arousal may be maximized by restructuring motivational state.     

The Role of Resonance in Performance Excellence and Life Engagement

This article presents a concept underlying excellence called resonance , which was developed based on research interviews and consulting practice with high-level performers from all walks of life. Findings suggest that many high-caliber performers follow a typical process as they become experts in their chosen field. They have a dream , which represents how they want to feel in their daily pursuits. They also engage in extensive preparation, which includes activities that enable them to live their dream. All of the participants faced obstacles, but they developed strategies to revisit their dream before they actually engaged in more preparation. This cyclical process that guided their performance and life has been termed resonance , which occurs when there is a seamless fit between their internal self and their external environment. It is captured in the resonance performance model (RPM), a heuristic model devised to guide the practice of consultants. The article also includes a discussion of the RPM in relation to other performance-related concepts such as flow, presents some recent and future research with resonance, and considers practical application for consultants who may be interested in using the RPM.     

Platonic Personal Immortality

I argue that Plato distinguishes between personal immortality and immortality of the soul. I begin by criticizing the consensus view that Plato identifies the person and the soul. I then turn to the issue of immortality. By considering passages from Symposium and Timaeus, I make the case that Plato thinks that while the soul is immortal by nature, if a person is going to be immortal, they must become so. Finally, I argue that Plato has a psychological continuity approach to personal identity. Thus, for Plato, a person becomes immortal by avoiding reincarnation and securing for themselves psychological continuity forever.     

Contextual interference and augmented feedback: is there an additive effect for motor learning?

Learning to perform a skilled behavior is affected by the context of the practice session and the frequency of augmented feedback. We studied the combined effect of these variables in the acquisition of a ballistic, bi-directional lever movement pattern involving four different target locations as measured by performance in practice, retention, and transfer tests. Augmented feedback was presented in either an every-trial or a faded schedule during random and blocked practice. Consistent with the contextual interference effect, the blocked practice group produced lower errors in acquisition, but the random practice group outperformed the blocked practice group in both retention and transfer. In contrast, faded feedback did not have a beneficial effect on learning and degraded learning when provided during blocked practice. While the results were consistent with previous findings of random and blocked practice, they were not consistent with previous findings of reduced feedback frequencies.     

Cognitive theory,cognitive impairment and clinical practice

The aim of this paper is to present a practical model for investigating cognitive impairment which integrates the experimental-cogaitive-information processing-theory and the psychometric-intellectual-abilities-tradition in psychology to understanding cognitive functioning. It reviews developments in cognitive theory in terms of Processes, complex and simple, such as Intelligence and Information Processing, and Factors of attained Level and Learning ability in the Verbal and Performance modalities. The Savage Cognitive Impairment Model (SCIM) is outlined and types of cognitive impairment defined. Measures of cognitive impairment relevant to clinical practice and research are presented.     

Vulnerability factors in depression: The facets of sociotropy and autonomy

Sociotropy-autonomy (Beck, 1983) describes a set of personality dimensions that relate to an individual's vulnerability to depression. Two recently developed scales, the Sociotropy-Autonomy Scale (Clark & Beck, 1991) and the Personal Style Inventory (Robinset al., 1994), have been developed in order to assess these personality dimensions. Typically, these measures are used in isolation and little published information is available concerning their interrelationship. The present study examined the relationship between the two scales and specified the various factors that emerge when the items of the two scales are integrated. Six hundred fifty-two participants responded to the Personal Style Inventory (Robinset al, 1994) and the Sociotropy-Autonomy Scale (Clark & Beck, 1991). A factor analysis on all of the items of the two scales revealed a five-factor structure (two sociotropy, two autonomy, and one achievement factor). The relationships among depression, the five derived factors, and the original scales developed by Clark and Beck (1991) and Robinset al. (1994) were critically examined. The results are discussed in the context of vulnerability to depression.     

Sustained attention in combat-related posttraumatic stress disorder

There is substantial evidence that PTSD patients have information processing abnormalities for stimuli that are highly relevant to the traumas they have endured. The goal of the present study was to examine whether this extends to neutral stimuli as well. Twenty-four male Vietnam combat veterans with PTSD were compared to fifteen normal male comparison subjects on their performance on a sensitive measure of sustained attention, the Continuous Performance Test-Identical Pairs version (CPT-IP). PTSD subjects did not differ from controls in their ability to discriminate target stimuli from background noise on the CPT. Additionally they performed as well as controls, even in the presence of external distraction. Thus, this study did not find a generalized deficit in attention associated with PTSD on the CPT-IP. Nevertheless, further clarification of the nature of the information processing disturbance in PTSD is warranted.     

The Reproduction of the Hypermasculine Male: Select Subaltern Views

Since the 1500s, masculinity and the socialization of men have been defined by colonization. This essay explores the hypermasculine male as a person unemotional yet fearful of intimacy, void of non-masculine attachments and identifications, competitive and aggressive, strong, independent, dominant, powerful, rational, sexist, homophobic, and generally disconnected from his own sense of self and the self of others. Nancy Chodorow’s challenge for the reproduction of masculinity is understood as a call to decolonialize the hypermasculine male as exposed in the political and subaltern psychologies of Frantz Fanon and Ashis Nandy. When the hypermasculine male is not rehumanized, all people are dehumanized, especially persons of color, children, women, and the elderly, and all who are perceived as not manly enough or as not following the rules and systems set by men. The image of the hypermasculine male is recognized in select computer games, where the image is actively promoted.
