Auditory Long term Memory: Repetition Priming of Voice Recognition

Two experiments examined repetition priming in the recognition of famous voices. In Experiment 1, reaction times for fame decisions to famous voice samples were shorter than in an unprimed condition, when voices were primed by a different voice sample of the same person having been presented in an earlier phase of the experiment. No effect of voice repetition was observed for non-famous voices. In Experiment 2, it was investigated whether this priming effect is voice-specific or whether it is related to post-perceptual processes in person recognition. Recognizing a famous voice was again primed by having earlier heard a different voice sample of that person. Although an earlier exposure to that person's name did not cause any priming, there was some indication of priming following an earlier exposure to that person's face. Finally, earlier exposure to the identical voice sample (as compared to a different voice sample from the same person) caused a considerable bias towards responding 'famous'-i.e. performance benefits for famous but costs for nonfamous voices. The findings suggestthat (1) repetition priming invoice recognition primarily involves the activation of perceptual representations of voices, and (2) it is important to determine the conditions in which priming causes bias effects that need to be disentangled from performance benefits.     

William King’s Influence on Locke’s Second Edition Change of Mind about Human Action and Freedom

ABSTRACT

Locke’s influential discussion of agency in the chapter ‘Of Power’ in the Essay Concerning Human Understanding underwent important changes between the first and second edition. He reconsidered many of his central claims about the mind’s deliberation about actions. Locke’s position in the two editions is not only different but, as he himself points out, sometimes incompatible. This has suggested to some commentators that his change of mind was at least partly due to an external influence. Locke himself gestures towards this conclusion in the new ‘Epistle’ in the second edition Essay. One view is that William Molyneux was a notable influence, while another position is that Ralph Cudworth’s work on free will, either directly or indirectly through the influence of his daughter Damaris Masham, was an important influence. The position I develop in this paper is that the strongest candidate for an important external influence on Locke’s second edition revision is Molyneux’s close associate and friend, Irish philosopher and Archbishop of Dublin, William King. I argue that King’s criticism is a plausible influence on Locke’s reconceptualization of will and desire. Finally, and perhaps most significantly, King’s criticism appears to have been instrumental in Locke’s new emphasis on the agent’s capacity to determine what to value.     

Postnatal development of respiratory and vocal responses during aversive classical conditioning in cats

Respiratory rate, respiration amplitude, and vocal responses were recorded in cats of different ages during classic conditioning. Vocal responses to the conditional stimulus (CS) appeared first in 8-week-old kittens, and became prominent at older ages. An increase in respiration rate occurred after the onset of the CS in cats of all ages. Similarly, the decrease of respiration amplitude was observed at all ages, but only in 8-week-old and older subjects did this response resemble an adult pattern. In 4-week-old kittens the response was characterized by an early and brief peak, suggesting an alpha conditional response (CR). Clear and significant discrimination between a warning and a safety signal was present in both respiratory and vocal responses after the age of 8 weeks.     

Depression in patients with spinal cord injuries: A synthesis of cognitive and somatic processes

Depression in some patients with spinal cord injuries may be clinically significant and, when present, should be treated to decrease morbidity including decreased physical functioning. Depression associated with spinal cord injury (SCI) may be misevaluated, due to (1) nonspecific multifactorial production of depression symptoms and (2) SCI-specific decrease in somatic sensory central nervous system input. The Somatic Suppression Hypothesis suggests that SCI patients have difficulty experiencing any intense emotion because of suppression of physiological arousal. In addition, cognitive processes that may reduce depression in SCI patients include: (1) attribution of somatic symptoms of depression to medical (biological) causes, (2) realistic, positive expectations for physical improvement, and (3) the perception that the disability of the SCI is only minimally related to the patient’s self-care after complete evaluation. Health personnel should accept lack of depression in SCI, and should encourage positive realistic expectations of recovery.     

Updating an object’s orientation and location during nonvisual navigation: A comparison between two processing modes

In the present study, we compared the effects of two processing modes on the updating of the location and orientation of a previously viewed object in space during a guided walk without vision. In Experiment 1, in order to measure the error for initial perception of object’s orientation, 12 subjects rotated a miniature model until it matched the memorized orientation of its counterpart object in space. In Experiment 2, they attempted either to keep track of the object continuously (in the object-centered [OC] task) or to estimate the object’s perspective only at the terminal vantage point given the trajectory they walked (in the trajectory-centered [TC] task). Subjects indicated the location of the object by facing it, and then rotated the model in order to indicate its orientation from the new vantage point. Results showed that, with respect to the TC mode, the OC mode induced a slowdown of the subjects’ self-paced locomotion velocity for both linear and angular movements, and a decrease of the latencies as well as smaller absolute errors for the orientation-of-the-object response. Mean signed errors on object’s orientation were equivalent for both processing modes, suggesting that the latter induced different allocations of processing resources on a common representation of space updated by “path integration.”     

A model for the study of research and education in a transdisciplinary context

In an evaluation project at the Goteborg University, we have looked at the relationship between individual and collective production of knowledge within the Health sciences in order to facilitate a common ground for a Academy of Health Sciences. We found obstacles for developing an environment which could stimulate multilateral co-operation and creativity. Some of these obstacles have their root in the different cultural backgrounds indicated in the analysis and makes it difficult to find common aims and strategies. The Model used makes the organizations’ activities visible and encouraging transdisciplinary contacts and improve organizational, structural and ideological decision making emanating from overall policies of the boards concerned.     

Effects of Viewing “Holocaust” on Germans and Americans: A Just-World Analysis1

This study examines attributions of blame to the Nazis and the Jews for the events of the holocaust. The sample consisted of Germans and Americans who had viewed the television series “Holocaust” and comparison groups who had not seen the program. It was found that among viewers who identified with the Nazis, attributions of blame to the Jews were higher than among nonviewers or viewers who identified with the Jews. Attributions of blame to the Nazis did not vary as a function of viewing the television series. However, people who identified with the Nazis blamed the Nazis less for the holocaust than people who identified with the Jews. These results are discussed in terms of the justworld hypothesis (Lerner & Miller, 1978) and their implications for media presentations on the victims of oppression.
