Markers’ influence on the duration discrimination of intermodal intervals

The effects of sensory signal characteristics on the duration discrimination of intermodal intervals was investigated in three experiments. Temporal intervals were marked by either the successive presentation of a visual then auditory signal (VA), or by the successive presentation of an auditory then visual signal (AV). The results indicated that (1) VA intervals are generally easier to discriminate than are AV intervals, but this effect depends on the range of duration studied; (2) AV intervals are perceived as longer than VA intervals for durations ranging from 250 to 750 msec; (3) the intensity of the visual markers for both AV and VA intervals does not affect the discrimination; and (4) the perceived duration of an intermodal interval is influenced by the length of the first and second markers. The results are mainly interpreted in terms of (1) a sensory trace left by visual and auditory signals and (2) the detection of these signals.     

Amnesia produced by anisomycin in an appetitive task is not due to conditioned aversion

Two experiments investigated the effects of lithium chloride (LiCl) and anisomycin (ANI) in a water reward Y-maze task. In Experiment 1, male CD-1 mice given weak or strong training were injected post-training with either saline or LiCl (150 mg/kg), which has been reported to produce conditioned aversion in mice. One day after training, both LiCl groups avoided the rewarded arm of the maze and drank less water than saline-injected controls. Two days after training, the strongly trained LiCl mice showed avoidance, while both LiCl groups drank less water. In Experiment 2, weakly trained mice given pre- and post-training ANI (30 mg/kg) were amnesic on the second test day compared to mice that received post-trial saline. However, water consumption was increased on the test day for both groups. LiCl produced a different pattern of results than ANI in this task. On the basis of these results, it is suggested that amnesia produced by ANI is due to impaired memory formation and not to conditioned aversion.     

A Bayesian marriage of science and politics

Conclusion Some might say that there is a sense in which the very consideration of whether science is equated with rationality is obscene. For far too long science has been dealt with by philosophers within the confines of a protectionist, if not an apologist, policy. Putnam has provided a service by exposing some of the weaker links of the scientism mythology. I have tried to bolster that critique by indicating how, along Bayesian lines, value and holistic considerations could be used to help positively transform science.Richard Rudner would have undoubtedly agreed with very little of what I have said — he seldon did. But he would have been there with open-mind and open-heart. Forqua mentor andqua friend he was, indeed, the philosopher par excellence.     

On being more than just a part of the whole: Regional identity and social distinctiveness

This article reports the results of a questionnaire study that examined the relationship between regional identification and perceptual accentuation of ingroup distinctiveness in a natural field setting. Respondents were male inhabitants of the Saarland which is a small German state. Half the respondents were members of the leading political party of the Saarland, while the other respondents were members of the major opposition party. As expected, the former showed more pronounced regional identification than the latter. Our main prediction was that a higher level of regional identification would be accompanied by stronger accentuation of positive distinctiveness of the regional ingroup relative to the national ingroup. The prediction was confirmed, both in terms of intergroup differentiation and perceived group homogeneity. Additional results suggest that, depending on the level of social identification, perceived group homogeneity may be either positively or negatively related to familiarity with the ingroup. Finally, we discuss the applicability of social identity theory to social contexts comprising differentially inclusive ingroups instead of mutually exclusive ingroups and outgroups.     

Testing alternative explanations for mortality salience effects: Terror management,value accessibility,or worrisome thoughts?

Previous research has shown that reminding subjects of their mortality encourages negative reactions to others whose behaviour or attitudes deviate from the cultural worldview (e.g. Greenberg, Pyszczynski, Solomon, Rosenblatt, Veeder, Kirkland and Lyon 1990; Greenberg, Simon, Pyszczynski, Solomon and Chatel 1992; Rosenblatt, Greenberg, Solomon, Pyszczynski and Lyon 1989). According to terror management theory, these findings result from a heightened need for faith in the cultural worldview that is activated by reminders of one's mortality. Study I assessed the plausibility of an alternative explanation which posits that mortality salience simply primes individuals' values. Whereas mortality salience led to harsher bond recommendations for a prostitute, a procedure that directly focused subjects on their values did not. Studies 2 and 3 assessed the possibility that reminding subjects of any worrisome future concern would produce the same effect as a reminder of mortality. In both studies, mortality salience led to negative reactions to a deviant and had no effect on self-reported affect, whereas other worrisome thoughts had no effect on reactions to a deviant but did create negative affect. Thus, consistent with terror management theory, mortality salience effects seem to result exclusively from thoughts of death.     

The perception of ingroup and outgroup homogeneity: On the confounding of group size,level of abstractness and frame of reference. A reply to Bartsch and Judd

In this reply, I criticize Bartsch and Judd's (1993) article on several grounds. First, they under-utilize the efforts undertaken in prior work to rule out the possibility of an inverse relation between group size and perceived group homogeneity as an alternative explanation of the observed ingroup homogeneity effect. Secondly, Bartsch and Judd's design doubles and thus aggravates the confounding problem. By trying to avoid the target group size confound, they end up with two other confounds involving level of abstractness and frame of reference. Finally, I criticize Bartsch and Judd's methodological advice to avoid within-subjects comparisons of ingroup and outgroup homogeneity in minority–majority contexts. Quite on the contrary, I highlight the socialpsychological significance of these comparisons.     

Syntactic priming: Investigating the mental representation of language

We argue that psycholinguistics should be concerned with both the representation and the processing of language. Recent experimental work on syntax in language comprehension has largely concentrated on the way in which language is processed, and has assumed that theoretical linguistics serves to determine the representation of language. In contrast, we advocate experimental work on the mental representation of grammatical knowledge, and argue that sybtactic priming is a promising way to do this. Syntactic priming is the phenomenon whereby exposure to a sentence with a particular syntactic construction can affect the subsequent processing of an otherwise unrelated sentence with the same (or, perhaps, related) structure, for reasons of that structure. We assess evidence for syntactic priming in corpora, and then consider experimental evidence for priming in production and comprehension, and for bidirectional priming between comprehension and production. This in particular strongly suggests that priming is tapping into linguistic knowledge itself, and is not just facilitating particular processes. The final section discusses the importance of priming evidence for any account of language construed as the mental representation of human linguistic capacities.The order of the first two authors is arbitrary.

Experiences of lecturers helping distressed students in higher education

Lecturers in higher education frequently attempt to support distressed students, yet most lecturers have no training in counselling. In order to gauge the extent to which lecturers are called upon to help distressed students, a survey was conducted of the experiences and opinions of lecturers in a British higher education institution. The incidence of helping students in distress appeared to be very high, almost all respondents (97%) having advised one or more distressed students during the twelve-month period preceding the survey. Further findings and implications of the survey are discussed.
