The role of motion in learning new faces

Four experiments are reported that investigate the usefulness of rigid (head nodding, shaking) and nonrigid (talking, expressions) motion for establishing new face representations of previously unfamiliar faces. Results show that viewing a face in motion leads to more accurate face learning, compared with viewing a single static image (Experiment 1). The advantage for viewing the face moving rigidly seems to be due to the different angles of view contained in these sequences (Experiment 2). However, the advantage for nonrigid motion is not simply due to multiple images (Experiment 3) and is not specifically linked to forwards motion but extends to reversed sequences (Experiment 4). Thus, although we have demonstrated beneficial effects of motion for face learning, they do not seem to be due to the specific dynamic properties of the sequences shown. Instead, the advantage for nonrigid motion may reflect increased attention to faces moving in a socially important manner.     

Aging and Remote Memory Declines: Preliminary Findings

Relatively little research has examined the effect of aging upon remote memory, especially among individuals who have entered their 10th decade of life. The present study examined whether remote memory deteriorates in a group of 132 neurologically normal men and women ranging in age from 50 to 97. Remote memory was measured with a modification of the Presidents Test. The data revealed that higher levels of education corresponded with better remote memory. Additionally, age-related differences in memory occurred only in men, with those aged 90 years and older showing significantly worse remote memory than other age groups. Potential explanations and implications of these data are delineated.     

Assessment of associative relations in alzheimer's disease: Evidence for preservation of semantic memory

Abstract

Semantic priming was assessed in Alzheimer's disease (AD), elderly control, and young control subjects with three lexical decision, continuous priming experiments. the stimuli were intracategory, associated pairs in Experiments 1 and 2 and varied types of associated pairs in Experiment 3. AD priming effects were equal to those of elderly control subjects; elderly and young control priming effects were also equal. We interpret this as evidence for the relative preservation of the semantic memory network in early AD, as in normal aging, at least to the extent necessary for normal access of concept nodes and normal automatic spreading activation between concept nodes. In a final study (Experiment 4) knowledge of the associations between the targets and related primes used in Experiments 1 and 2 was explicitly assessed; 20 out of 22 AD subjects showed perfect or close to perfect performance.     

An exploration into the influence of academic and social values, procrastination, and perceived school belongingness on academic performance

The results of a structural equation model showed that a tendency to procrastinate, assessed early in college students’ first term, was positively related to social values, assessed as concerns over social exclusion, but was negatively related to academic task values and grade goal-setting. The results suggest that procrastination may be a partial mediator of the influence of academic and social values on perceived school belongingness. In addition, the tendency to procrastinate had a direct negative relationship with self-regulatory self-efficacy and perceived school belongingness and was positively related to perceived stress near the end of the term. There was also a statistically significant negative total effect of procrastination on performance-approach and mastery-approach goal orientation and end-of-term grade point average (GPA). Statistically significant positive total effects of performance-approach and mastery-approach achievement goal orientations on GPA were found. However, while a statistically significant direct positive effect of performance-approach orientation on GPA was found, a direct relationship between mastery-approach orientation and GPA was not statistically significant.     

Neuroethics,confidentiality, and a cultural imperative in early onset Alzheimer disease: a case study with a First Nation population

The meaningful consideration of cultural practices, values and beliefs is a necessary component in the effective translation of advancements in neuroscience to clinical practice and public discourse. Society’s immense investment in biomedical science and technology, in conjunction with an increasingly diverse socio-cultural landscape, necessitates the study of how potential discoveries in neurodegenerative diseases such as Alzheimer disease are perceived and utilized across cultures. Building on the work of neuroscientists, ethicists and philosophers, we argue that the growing field of neuroethics provides a pragmatic and constructive pathway to guide advancements in neuroscience in a manner that is culturally nuanced and relevant. Here we review a case study of one issue in culturally oriented neuroscience research where it is evident that traditional research ethics must be broadened and the values and needs of diverse populations considered for meaningful and relevant research practices. A global approach to neuroethics has the potential to furnish critical engagement with cultural considerations of advancements in neuroscience.     

Science versus orthodoxy: Anatomy of the congressional condemnation of a scientific article and reflections on remedies for future ideological attacks

In July 1999 the U.S. Congress passed a formal resolution condemning our article on child sexual abuse (CSA), an article in which we concluded, based on 59 meta-analytically reviewed studies using college samples, that the assumed harmfulness of CSA had been overstated (Rind, Tromovitch, & Bauserman, 1998). The condemnation followed months of attacks by social conservatives and by mental health professionals specializing either in curing homosexuality or in treating patients by inducing them to recover memories of CSA. In this article, we detail the chronology behind the attacks. Then we discuss the science behind our meta-analysis, showing that the attacks were specious and that our study employed sound science, advancing the field considerably by close attention to issues of external, internal, and construct validity, as well as precision and objectivity. Next, we discuss orthodoxies and moral panics more generally, arguing that our article was attacked as vehemently as it was because it collided with a powerful, but socially constructed orthodoxy that has evolved over the last quarter century. Finally, we offer reflections and recommendations for fellow researchers, lest this kind of event recur. We focus on the need for greater cognizance of historical attacks on science to anticipate and deflate future attacks. We argue that our research should stand as another reminder among many that sacred-cow issues do not belong in science. We discuss nonscientific advocacy in the social sciences and the need to recognize and counter it. We discuss the failure of psychology to adequately deal with the study of human sexuality, a problem that enabled the faulty attacks on our article, and we suggest directions for becoming more scientific in this area. And last, we raise the issue of how professional organizations might deal more effectively with such attacks in the future.     

Sweetening the Till: The Use of Candy to Increase Restaurant Tipping1

A common practice among servers in restaurants is to give their dining parties an unexpected gift in the form of candy when delivering the check. Two experiments were conducted to evaluate the impact of this gesture on the tip percentages received by servers. Experiment 1 found that customers who received a small piece of chocolate along with the check tipped more than did customers who received no candy. Experiment 2 found that tips varied with the amount of the candy given to the customers as well as with the manner in which it was offered. It is argued that reciprocity is a stronger explanation for these findings than either impression management or the good mood effect.     

Theory of mind and epistemological development: the relation between children's second-order false-belief understanding and their ability to reason about evidence

The study investigates the hypothesis that children's ability to attribute second-order beliefs facilitates their understanding of evidence, as seen in the ability to distinguish between causes and reasons. Seventy-four children 5–7 yr old were given belief and evidence tests. The belief tests assessed their ability to represent and reason from second-order false-beliefs, and the evidence tests assessed their ability to distinguish between the cause of a situation and a person's reason for believing it. The relation between performance on the two tests was determined, taking into account general language and non-verbal reasoning abilities. Results show that performance on the belief test and on the evidence part of the evidence test improved significantly over the age range, and that a significant proportion of variance in the evidence test scores is accounted for by second-order false-belief understanding, over and above that accounted for by general language and non-verbal abilities. The argument is made that second-order false-belief understanding is fundamental to children's epistemological development, underlying not just their understanding of evidence, but also their understanding of inference and truth.     

“Statistical,” “Practical,” and “Clinical”: How Many Kinds of Significance Do Counselors Need to Consider?

The present article reviews and distinguishes 3 related but different types of significance: “statistical,” “practical,” and “clinical.” A framework for conceptualizing the many “practical” effect size indices is described. Several effect size indices that counseling researchers can use, or that counselors reading the literature may encounter, are summarized. A way of estimating “corrected” intervention effects is proposed. It is suggested that readers should expect authors to report indices of “practical” or “clinical” significance, or both, within their research reports; and it is noted that indeed some journals now require such reports.     

Psychological Adjustment to Breast Cancer

Breast cancer remains a highly prevalent and extraordinarily stressful experience for hundreds of thousands of women each year in the United States and around the world. Psychological research has provided a picture of the emotional and social impact of breast cancer on patients' lives, and of factors associated with better versus worse adjustment. Psychosocial interventions have been beneficial in decreasing patients' distress and enhancing their quality of life. Recent research also suggests that psychological factors may be related to potentially important biological disease-related processes. In addition to providing an understanding of the psychological factors in breast cancer, research in this area has provided a framework for research on adaptation to health-related stress in general.
