Conditional advice and inducements: are readers sensitive to implicit speech acts during comprehension?

Conditionals can implicitly convey a range of speech acts including promises, tips, threats and warnings. These are traditionally divided into the broader categories of advice (tips and warnings) and inducements (promises and threats). One consequence of this distinction is that speech acts from within the same category should be harder to differentiate than those from different categories. We examined this in two self-paced reading experiments. Experiment 1 revealed a rapid processing penalty when inducements (promises) and advice (tips) were anaphorically referenced using a mismatching speech act. In Experiment 2 a delayed penalty was observed when a speech act (promise or threat) was referenced by a mismatching speech act from the same category of inducements. This suggests that speech acts from the same category are harder to discriminate than those from different categories. Our findings not only support a semantic distinction between speech act categories, but also reveal pragmatic differences within categories.     

Gender differences in unrealistic optimism about marriage and divorce: are men more optimistic and women more realistic?

Two studies (n = 497) examine gender differences in "unrealistic optimism" in beliefs of marriage using a Taiwanese population. Unrealistic optimism is defined as the beliefs that positive (negative) events are more (less) likely to happen to one's self versus others. Although the bias is robust, it has been shown to be lower among people with an interdependent orientation, specifically those from a collectivist culture (e.g., Taiwan). We find that the unrealistic optimism bias is stronger (Study 1) and more resilient to change when base rates are provided (Study 2) for men as compared to women. Results are consistent with the interpretation that men have a less relationally interdependent self-construal than women. Theoretical implications for unrealistic optimism, cross-cultural psychology, as well as gender differences are discussed.     

Religiosity and obesity: are overweight people more religious?

The present study was undertaken to test the recently advanced hypothesis that highly religious people are more prone to obesity than is true for people in general. Based on a sample of over 6000 middle- to older-aged women, the study found essentially no support for the hypothesis. The only possible exception was in the case of members of certain denominations with historically high birth rates.     

How sensitive are handedness prevalence figures to differences in questionnaire classification procedures?

Questionnaire data from 572 subjects show that the proportion of right-handers to nonright-handers varies greatly (from 1:100 to 92:8) as a function of questionnaire length, graded or forced response to items, and cut-off criteria. For this reason, the right-handed/nonright-hander dichotomy is singularly unsuited as a basis for classification when handedness is to be related to some other neuropsychological factor as an independent variable. This is especially the case when very strict cut-off criteria are used to define right-handedness (e.g., only those individuals who prefer the right hand for all activities listed).     

Effects of similarity and repetition on memory: registration without learning?

We investigated judgments of the frequency of test items (Y) that were highly similar to studied items (X) to test a prediction made by several memory models: that the judged frequency of Y should be proportional to the judged frequency of X. Whether stimuli were pictures or words, judged frequency of Y was bimodally distributed with 1 mode at zero, suggesting that frequency judgments involve a 2-stage process in which a zero judgment is made if there is a mismatch between retrieved information and the test item. Nonzero judgements, taken by themselves, were consistent with the prediction of proportionality. In 2 experiments, the percentage of zero judgments made to Y increased with repetition of X, but in 2 others the percentage did not change beyond frequency = 1. The percentage of "new" judgments in recognition memory followed this same pattern. Because the judged frequency of X increased even as X-Y discrimination showed no improvement, we characterize the result as "registration without learning."     

Transfer in discrimination learning: Do children mediate more than adults?

A series of four-dimensional, discrimination-learning problems were presented to second-, sixth-, eighth-, and twelfth-grade students (ages 7, 11, 13, and 17 years, respectively). One pretraining problem, using different dimensions, preceded the four experimental problems; these employed identical dimensions and stimulus values. Solutions were selected without dimensional replacement.Blank-trial probes enabled detection of initial predictions. Results clearly indicated that (1) older subjects made dramatically fewer intradimensional predictions (utilizing the solution dimension from the preceding problem) than did younger subjects, (2) all age groups demonstrated systematic changes over problems; these reflected the specific solution sequence experienced, and (3) there were consistent developmental differences in the speed with which subjects noted and utilized regularities across problems.The pattern of data is not congruent with the expectations of mediation theory. However, it is in accord with the transfer hypothesis, which is a recent extension of hypothesis theory. The transfer hypothesis provides a theoretical framework which suggests when we should observe “mediational” behavior (i.e., intradimensional transfer) and when to expect the inverse.     

Avoiding misinterpretations of Piaget and Vygotsky: Mathematical teaching without learning,learning without teaching,or helpful learning-path teaching?

This article provides an overview of some perspectives about special issues in classroom mathematical teaching and learning that have stemmed from the huge explosion of research in children's mathematical thinking stimulated by Piaget. It concentrates on issues that are particularly important for less-advanced learners and for those who might be having special difficulties in learning mathematics. A major goal of the article is to develop a framework for understanding what effective mathematics teaching and learning is, because doing so is so important for struggling students and for research about them. Piaget's research had a fundamental influence on the on-going tension between understanding and fluency in the classroom, supporting efforts toward increasing understanding. But in some countries, misinterpretations of Piaget led to practices that are counterproductive for children, especially struggling learners. Such misinterpretations are identified and a more balanced approach that also draws on Vygotsky is described—a learning-path developmentally-appropriate learning/teaching approach.     

Family resemblances in conservatism: Are daughters more similar to parents than sons are?1

Family resemblances in conservatism were examined for a sample of 176 families tested in metropolitan Adelaide in 1972. Each family member's score on the Wilson and Patterson Conservatism Scale was compared with the scores of other members of his or her family. Using this within-family analysis it was found, as predicted, that there were family resemblances in conservatism and that sons were less similar to their parents in conservatism than were daughters. There was no evidence to support same-sex modeling. Results also suggested that the similarity of daughters to fathers was reduced in lower SES families. Parents were more conservative than their children and females were more conservative than males. Results were discussed in relation to developmental influences and to the literature on sex differences.     

The development of expert face processing: are infants sensitive to normal differences in second-order relational information?

Sensitivity to second-order relational information (i.e., spatial relations among features such as the distance between eyes) is a vital part of achieving expertise with face processing. Prior research is unclear on whether infants are sensitive to second-order differences seen in typical human populations. In the current experiments, we examined whether infants are sensitive to changes in the space between the eyes and between the nose and the mouth that are within the normal range of variability in Caucasian female faces. In Experiment 1, 7-month-olds detected these changes in second-order relational information. Experiment 2 extended this finding to 5-month-olds and also found that infants detect second-order relations in upright faces but not in inverted faces, thereby exhibiting an inversion effect that has been considered to be a hallmark of second-order relational processing during adulthood. These results suggest that infants as young as 5 months are sensitive to second-order relational changes that are within the normal range of human variability. They also indicate that at least rudimentary aspects of face processing expertise are available early in life.     

Evaluation and reinforcement: What do males and females really want to hear?

This research was designed to note if males and females differ in their choices of the reinforcement and evaluation they assign to others. Thirty-one male and 31 female subjects viewed four videotapes of skilled and unskilled male and female speakers. Subjects assigned 10 of 40 statements varying in reinforcement value to each speaker and completed a five-item evaluation for each speech. Participants also completed a four-item measure to determine if they selected comments that they too would want to receive. Results indicated that males desire more positive reinforcement than females, although the two genders do not differ in their selection of evaluation. Also, subjects agreed that statements they selected were those they would find acceptable if applied to them.     

Fear of failure in males: A more salient factor than fear of success in females?

Sex differences in self-attributions following winning or losing in a highly competitive achievement-type situation were investigated. Subjects competed in same- or mixed-sex pairs on an anagram task which was prearranged in difficulty so that one subject would clearly defeat his/her partner. A significant sex of subject × outcome interaction emerged. Males were more likely to attribute their successes to skill and failures to luck. Females attributed both their successes and failures to a relatively equal amount of skill. This self-defensive bias in males was interpreted as indicating a greater fear of failure in males. The relatively rational and objective attributions of females did not support a female fear of success hypothesis. No significant interactions with sex of partner on this variable were found. Finally, subjects were asked to rate their opponents on a series of personality, attractiveness, and happiness dimensions. Neither males nor females were differentially evaluated as a function of winning or losing.The research reported here was partially supported by a grant to the first author from the California State University, Fresno Foundation.     

The unresponsive bystander: are bystanders more responsive in dangerous emergencies?

Previous research in bystander intervention found that the presence of other bystanders reduces helping behaviour in an emergency (bystander effect). This research was mainly conducted in the context of non‐dangerous, non‐violent emergencies. We hypothesize that the classic bystander effect does not occur in more dangerous situations because: a) they are faster and more clearly recognized as emergency situations; and b) higher costs for refusing help increase the accepted costs for helping. Following this line of reasoning, the present research tests whether the bystander effect is affected by the degree of the emergency's potential danger. Results supported our expectations: In situations with low potential danger, more help was given in the solitary condition than in the bystander condition. However, in situations with high potential danger, participants confronted with an emergency alone or in the presence of another bystander were similarly likely to help the victim.

Somatic Markers and Response Reversal: Is There Orbitofrontal Cortex Dysfunction in Boys with Psychopathic Tendencies?

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex functioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.     

Learning and adult neurogenesis: survival with or without proliferation?

Recent high quality papers have renewed interest in the phenomenon of neurogenesis within the adult mammalian brain. Many studies now show that neurogenesis can be modulated by environmental factors including physical activity, stress, and learning. These findings have considerable implications for neuroscience in general, including the study of learning and memory, neural network plasticity, aging, neurodegeneration, and the recovery from brain injury. Although new light has been shed on this field, many contradictory findings have been reported. Here we propose two principle issues which underlie these inconsistencies, with particular focus on the interaction between learning and neurogenesis. The first issue relates to the basic methodology of measuring the generation of new brain cells, i.e., proliferation, as compared to survival of the newly made cells. Mostly, measures of neurogenesis reported are a combination of proliferation and survival, making it impossible to distinguish between these separate processes. The second aspect is in regards to the role of environmental factors which can affect both proliferation and survival independently. Especially the interaction between stress and learning is of importance since these might counteract each other in some circumstances. Reviewing the literature while taking these issues into account indicates that, in contrast to some findings, cell proliferation in the dentate gyrus of the hippocampus as a result of learning cannot be ruled out yet. On the other hand, increased survival of granule cells in the dentate gyrus as a result of hippocampal-dependent learning has been clearly demonstrated. Moreover, this learning-induced survival of granule cells, which were born before the actual learning experience, might provide a molecular mechanism for the 'use it or lose it' principle.     

Stress and cytokine effects on learning: What does sex have to do with it?

Many studies have alluded to sexually dimorphic changes in behavior following stress. Although many have suggested that these changes are a function of stress-induced changes in learning and memory, there are questions regarding whether performance in those learning and memory tasks are influenced by stress-induced changes in drive more than in actual learning and memory processes. We used the classically conditioned eyeblink response (CCER) to determine whether slowed learning following stress in females can be explained by changes in unconditional response (UR) amplitude, a sign of a stress-induced shift in sensory reactivity. In addition, we had a second treatment group injected with the pro-inflammatory cytokine IL-1β to serve as an interoceptive stress condition, a physiological stressor with minimal stimulation to the animal. Replicating the work by Shors and colleagues, we found that stressed female rats had slower acquisition of the conditioned response (CR), but we also found that an IL-1β injection leads to a slowing of CR acquisition. However, in both cases, UR amplitude was lower in the treatment groups. We followed up these results by testing sensory reactivity through the acoustic startle response (ASR), where the magnitude of the ASR was marginally, but nonsignificantly, reduced by the same dose regimen of IL-1β. Together, these experiments suggest that tailshock stress and immune signaling (IL-1β) reduce sensory reactivity and the saliency of the stimuli used in the CCER, leading to slower learning in female rats.     

Terror salience and punishment: Does terror salience induce threat to social order?

In recent times, international terrorism has become one of the most serious concerns of the modern Western world. As a consequence, the risk and fear of terrorism is more salient in people’s minds (i.e. terror salience), which is supposed to affect behavioral responses in our society. The present research suggests that increased punishment of violations of criminal laws is one societal reaction to increased terror salience. It was consistently shown that increased terror salience, induced by either varying the temporal distance from the London terrorist attacks of July 7, 2005 (Study 1), by vignettes in the form of newspaper articles manipulating the expected terror risk (Study 2), or by pictures of recent terrorist attacks (Studies 3 and 4), significantly increased the punishment assigned to a violation of criminal laws that was completely unrelated to terror (i.e. car theft and rape). Finally, Study 4 revealed that (a) the effect of terror salience on punishment is indeed due to increased perception of threat to social order and (b) that this effect cannot be explained by the general negative nature of the stimulus material employed in this study.
