Actual Memory Ability Significantly Predicts Self-Evaluations of Memory

A number of researchers have suggested that confidence in one's memory is extremely flexible and that self-evaluations may actually reflect the difficulty of the memory task - rather than one's actual memory skill. This study examined this effect and related confidence in one's memory to actual memory skill, as measured by standardized neuropsychological tests of memory. We found that, indeed, confidence in one's memory can be altered. However, we observed that the best predictor of self-evaluation of memory was, in fact, actual memory skill as measured by standardized tests. We suggest that self-evaluation of memory and confidence in one's memory accurately reflects memory skill,although this evaluation can be slightly affected by the difficulty with which the memory is retrieved.

Can I Do It? Will I Try? Personal Efficacy,Assigned Goals,and Performance Norms as Motivators of Individual Performance1

This study tested concurrent influences of personal efficacy, assigned goals, and performance norms on individual performance, mediated by personal goals and task‐specific self‐efficacy. Seventy‐seven undergraduate students performed a verbal task in this laboratory experiment that manipulated assigned goal level (low, high) and information about the performance of others (low, high). Relations among variables, including general, domain, and task‐specific self‐efficacy, as well as performance were examined through structural equation modeling. Results demonstrated simultaneous effects of assigned goals and normative information on self‐efficacy, personal goals, and subsequent performance, as well as mediated effects of domain efficacy on performance.     

The pleasures of uncertainty: prolonging positive moods in ways people do not anticipate

The authors hypothesized that uncertainty following a positive event prolongs the pleasure it causes and that people are generally unaware of this effect of uncertainty. In 3 experimental settings, people experienced a positive event (e.g., received an unexpected gift of a dollar coin attached to an index card) under conditions of certainty or uncertainty (e.g., it was easy or difficult to make sense of the text on the card). As predicted, people's positive moods lasted longer in the uncertain conditions. The results were consistent with a pleasure paradox, whereby the cognitive processes used to make sense of positive events reduce the pleasure people obtain from them. Forecasters seemed unaware of this paradox; they overwhelmingly preferred to be in the certain conditions and tended to predict that they would be in better moods in these conditions.     

WARRANTED ASSERTIBILITY AND THE NORMS OF ASSERTORIC PRACTICE: WHY TRUTH AND WARRANTED ASSERTIBILITY ARE NOT COINCIDENT NORMS

Crispin Wright has argued that truth and warranted assertibility are coincident but non‐co‐extensive norms of assertoric practice and that this fact inflates deflationary theories of truth. Wright's inflationary argument has generated much discussion in the literature. By contrast, relatively little has been said about the coincidence claim that is the focus of this paper. Wright's argument for the claim that truth and warranted assertibility are coincident norms is first presented. It is then suggested that the argument trades on an ambiguity in ‘justified’ and ‘warrantedly assertible’. Finally, it is argued that, once the ambiguity is removed, there is reason to reject the claim that truth and epistemic warrant are coincident norms of assertoric practice. One important result is that no epistemic theory of truth can satisfy what Wright takes to be a key platitude about assertion.     

Gender differences in anger and fear as a function of situational context

Gender differences in the reported intensity of anger and fear toward hypothetical males and females were explored in three age groups (6–12 year olds, 14–16 year olds, and adults over 30) located in two different geographic areas. The samples were primarily Caucasian and included a wide range of socioeconomic groups. Subjects reported on the intensity of feelings elicited by characters in an emotion story task in which three aspects of situational context were varied: the gender of the story characters eliciting the feeling (all situations), the stereotypic gender-typed or cross-gender behavior of the eliciting character (four situations), and the affective quality of the situations (four situations). Across all three age groups, situations that were frightening, anger-provoking, or that depicted stereotypic male-negative behavior elicited the most consistent subject gender and character gender differences in reported fear and anger. Relative to males, females of all ages reported more fear in frightening, anger-producing, and male-negative stereotypic situations. Males were reported to be more frightening and anger-producing than were females in those same situations. The data also suggested that with development, females reported less intense fear of females, while males reported less intense fear of males.This research was supported by a Gender Roles grant from the Rockefeller Foundation. We appreciate their support. We would also like to thank the public school systems of Milton, Norwood, and Watertown, Massachusetts, and Saskatoon, Saskatchewan, Canada. Finally, we would like to thank Lance Davidow, John Houlihan, and Theodore Cross for statistical consultation and/or computer programming, as well as all the parents, children, and adolescents who participated in the study.     

Dissociating Basal Forebrain and Medial Temporal Amnesic Syndromes: Insights from Classical Conditioning

In humans, anterograde amnesia can result from damage to the medial temporal (MT) lobes (including hippocampus), as well as to other brain areas such as basal forebrain. Results from animal classical conditioning studies suggest that there may be qualitative differences in the memory impairment following MT vs. basal forebrain damage. Specifically, delay eyeblink conditioning is spared after MT damage in animals and humans, but impaired in animals with basal forebrain damage. Recently, we have likewise shown delay eyeblink conditioning impairment in humans with amnesia following anterior communicating artery (ACoA) aneurysm rupture, which damages the basal forebrain. Another associative learning task, a computer-based concurrent visual discrimination, also appears to be spared in MT amnesia while ACoA amnesics are slower to learn the discriminations. Conversely, animal and computational models suggest that, even though MT amnesics may learn quickly, they may learn qualitatively differently from controls, and these differences may result in impaired transfer when familiar information is presented in novel combinations. Our initial data suggests such a two-phase learning and transfer task may provide a double dissociation between MT amnesics (spared initial learning but impaired transfer) and ACoA amnesics (slow initial learning but spared transfer). Together, these emerging data suggest that there are subtle but dissociable differences in the amnesic syndrome following damage to the MT lobes vs. basal forebrain, and that these differences may be most visible in non-declarative tasks such as eyeblink classical conditioning and simple associative learning.     

The Meaning of Brand Names to Children: A Developmental Investigation

We explored the way that children use brand names in making consumer judgments. Brand names can serve as a simple perceptual cue that identifies a product as one people are familiar with or one they associate with certain perceptual features. Brands can also be associated with symbolic or conceptual meanings, conveying status, prestige, or trendiness. We proposed that young children relate to brands on a perceptual level, whereas older children relate to brands on a conceptual basis as well. We examined this proposition in an experiment conducted with children 8,12, and 16 years of age. Participants were asked to evaluate an advertised product (e.g., athletic shoes) with a familiar brand name that was either popular (e.g., Nike^®) or less popular (e.g., Kmart^®). The advertised product was physically identical in both cases, allowing us to explore whether the brand name had meaning for children apart from its name familiarity or perceptual features. The use of conceptual brand meanings was assessed by asking participants to make several types of brand‐related judgments including evaluations of the advertised product, impressions of the owners of the advertised product, and evaluations of possible extensions of the popular brand name advertised. Results indicate that by the time children reach 12 years of age, they use brand names as an important conceptual cue in consumer judgments.     

Role of the Leader in Therapy Groups Conducted With Illicit Drug Abusers: How Directive Does the Leader Have to Be?

A 17-hour marathon group was conducted in a residential treatment center established for inmates in a correctional setting in the southeastern United States. The Hill Interaction Matrix (HIM-G; Hill, 1965) was used to measure the types of leader activity and the types of member activity during portions of each hour of the group activity. It was found that when the group was most therapeutic, there was a relationship between the therapists' actions and behaviors and the types of issues that were discussed in the group. The results that were found do not agree with some of the established drug and alcohol abuse literature.     

The ontogenesis of lateralized behavior in the domestic cat, Felis silvestris catus

For the first time, the development of paw preferences in the domestic cat, Felis silvestris catus, is explored. Twelve cats were tested at ages 12 weeks, 6 months, and 1 year on a challenge requiring them to use one of their paws to retrieve food. To control for repeated testing of the same cats at different ages, the subjects' paw preferences were compared with those of cats tested just once, at 6 months (n = 11) or 1 year (n = 14) of age. Analysis revealed a significant effect of age on the distribution of cats' paw preferences. Cats were significantly more likely to be ambilateral than paw preferent at 12 weeks and at 6 months but more likely to display a lateral bias in paw use at 1 year. There was a significant positive correlation between cats' paw preferences at 6 months and at 1 year. Lateralized behavior was strongly sex related. Females had a greater preference for using their right paw; males were significantly more inclined to adopt their left. Analysis revealed no significant difference in the direction or strength of paw preferences of cats tested longitudinally or cross-sectionally at 6 months or 1 year of age. Findings indicate that cats develop paw preferences by 1 year and hint at a relative stability in preferred paw use over time. The strong sex effect observed strengthens the case for the influence of a biological mechanism in the emergence of motor asymmetry in cats.
