Current behavior modification in the classroom: be still, be quiet, be docile

Classrooms have recently been criticized as total institutions where there is a rigid preoccupation with order and control, and where children are required to be still, to be silent, and to obey. Behavior modification has been described as a major source of change in the classroom. A review of this journal's papers on behavior modification in the classroom indicated that inappropriate behavior has been consistently defined as behavior that interferes with order, quiet, and stillness. It is argued therefore, that behavior modification has supported rather than changed the questionable status quo. Alternative areas for behavior modification in traditional classrooms and the role of behavior modification in the development of open classrooms are discussed.     

Event-related brain potentials reflect traces of echoic memory in humans

In sequences of identical auditory stimuli, infrequent deviant stimuli elicit an event-related brain potential component called mismatch negativity (MMN). MMN is presumed to reflect the existence of a memory trace of the frequent stimulus at the moment of presentation of the infrequent stimulus. This hypothesis was tested by applying the recognition-masking paradigm of cognitive psychology. In this paradigm, a masking sound presented shortly before or after a test stimulus diminishes the recognition memory of this stimulus, the more so the shorter the interval between the test and masking stimuli. This interval was varied in the present study. It was found that the MMN amplitude strongly correlated with the subject’s ability to discriminate between frequent and infrequent stimuli. This result strongly suggests that MMN providesa measure for a trace of sensory memory, and further, that with MMN, this memory can be studied without performance-related distortions.     

Expert face coding: Configural and component coding of own-race and other-race faces

Configural and holistic coding are hallmarks of face perception. Although recent studies have shown that own-race faces are coded more holistically than other-race faces, the evidence for better configural coding of own-race faces is equivocal. We directly measured configural and component coding of own- and other-race male faces in Caucasian and Chinese participants. We manipulated individual features (components) or their spatial relations (configurations) using a novel morphing method to vary difficulty parametrically and tested sensitivity to these changes in a sequential matching task. Both configural and component coding were better for upright own-race than for upright other-race faces. Inversion impaired detection of configural changes more than it did detection of component changes, but also impaired performance more for easier discriminations,independent of type of change. These results challenge explanations of face expertise that rely solely on configural and holistic processing, and also call into question the widespread interpretation of large inversion decrements as diagnostic of configural coding.     

The concept of auditory stimulus representation in cognitive neuroscience

The sequence of neurophysiological processes elicited in the auditory system by a sound is analyzed in search of the stage at which the processes carrying sensory information cross the borderline beyond which they directly underlie sound perception. Neurophysiological data suggest that this transition occurs when the sensory input is mapped onto the physiological basis of sensory memory in the auditory cortex. At this point, the sensory information carried by the stimulus-elicited process corresponds, for the first time, to that contained by the actual sound percept. Before this stage, the sensory stimulus code is fragmentary, lacks the time dimension, cannot enter conscious perception, and is not accessible to top-down processes (voluntary mental operations). On these grounds, 2 distinct stages of auditory sensory processing, prerepresentational and representational, can be distinguished.     

Rules of Meaning and Practical Reasoning

Can there be rules of language which serve both to determine meaning and to guide speakers in ordinary linguistic usage, i.e., in the production of speech acts? We argue that the answer is no. We take the guiding function of rules to be the function of serving as reasons for actions, and the question of guidance is then considered within the framework of practical reasoning. It turns out that those rules that can serve as reasons for linguistic utterances cannot be considered as normative or meaning determining. Acceptance of such a rule is simply equivalent to a belief about meaning, and does not even presuppose that meaning is determined by rules. Rules that can determine meaning, on the other hand, i.e., rules that can be regarded as constitutive of meaning, are not capable of guiding speakers in the ordinary performance of speech acts.     

Representing AIDS

AIDS has contributed to changes in how our society constructs its image of death. In the early 1980s Philippe Ariès argued that death and the symbols surrounding it had been “relegated to the secret, private space of the home or the hospital.” With the coming of AIDS, death demands its place in the public mind - and eye. Many artists have devoted their talents to making AIDS visible. In doing so, they have resurrected many questions about sexuality and mortality. This paper discusses several examples of current AIDS art and places them in a wider cultural and historical context.     

Abortion and victimisability

ABSTRACT This paper begins with a review of major difficulties with both extreme conservative and extreme liberal views on foetal moral status and the morality of abortion. There follows an outline and defence of a moderate position on abortion which is centred in an account of emergent foetal victimisability in being killed. Lastly, various perplexities about this view are explored, particularly the question whether, once victimisable at all, the victimisability of a foetus should reasonably be thought to increase proportionately with further biological development.     

From sensory to long-term memory: evidence from auditory memory reactivation studies

Everyday experience tells us that some types of auditory sensory information are retained for long periods of time. For example, we are able to recognize friends by their voice alone or identify the source of familiar noises even years after we last heard the sounds. It is thus somewhat surprising that the results of most studies of auditory sensory memory show that acoustic details, such as the pitch of a tone, fade from memory in ca. 10-15 s. One should, therefore, ask (1) what types of acoustic information can be retained for a longer term, (2) what circumstances allow or help the formation of durable memory records for acoustic details, and (3) how such memory records can be accessed. The present review discusses the results of experiments that used a model of auditory recognition, the auditory memory reactivation paradigm. Results obtained with this paradigm suggest that the brain stores features of individual sounds embedded within representations of acoustic regularities that have been detected for the sound patterns and sequences in which the sounds appeared. Thus, sounds closely linked with their auditory context are more likely to be remembered. The representations of acoustic regularities are automatically activated by matching sounds, enabling object recognition.     

An integrated model of group psychotherapy for patients with fibromyalgia

This study examined the effectiveness of an integrated model of brief group psychotherapy for treatment of fibromyalgia syndrome, using cognitive behavioral and supportive expressive techniques. In the context of an outpatient, multidisciplinary fibromyalgia treatment program, group psychotherapy was provided to 35 patients with 21 control patients. Pre-post treatment measures of depression, anxiety, fibromyalgia impact, pain, fatigue, and morning tiredness were obtained. Using a quasi-experimental design with validated psychometric instruments, the results showed a significant decrease in pre-versus post treatment measures of depression, fibromyalgia impact, fatigue, and pain for the treatment patients, suggesting that an integrated model of group psychotherapy may have beneficial psychological and functional effects for some patients with fibromyalgia.
