The role of eye movements in subitizing and counting

Previous work has suggested that eye movements may be necessary for accurate enumeration beyond the subitization range of about 4 items. This study determined the frequency of eye movements normally made during enumeration, their relationship to response times, and whether they are required for accurate performance. This was achieved by monitoring eye movements and comparing performance when observers were allowed to saccade and when they were not. The results showed that (a) there was a sharp increase in saccadic frequency beyond about 4 items (from < 0.2 saccades per item to about 1 per item), and (b) enumeration of fewer than 4 items remained rapid and accurate even when eye movements were prevented, whereas enumeration beyond this became less efficient and sometimes less accurate. The results are discussed in relation to the memory and processing requirements of enumeration tasks.     

Cancer and the threat of death: the cognitive dynamics of death-thought suppression and its impact on behavioral health intentions

Five studies examined the cognitive association between thoughts of cancer and thoughts of death and their implication for screening intentions. Study 1 found that explicit contemplation of cancer did not increase death-thought accessibility. In support of the hypothesis that this reflects suppression of death-related thoughts, Study 2 found that individuals who thought about cancer exhibited elevated death-thought accessibility under high cognitive load, and Study 3 demonstrated that subliminal primes of the word cancer led to increased death-thought accessibility. Study 4 revealed lower levels of death-thought accessibility when perceived vulnerability to cancer was high, once again suggesting suppression of death-related thoughts in response to conscious threats associated with cancer. Study 5 extended the analysis by finding that after cancer salience, high cognitive load, which presumably disrupts suppression of the association between cancer and death, decreased cancer-related self-exam intentions. Theoretical and practical implications for understanding terror management, priming and suppression, and responses to cancer are discussed.     

How Do Children Stigmatize People With Mental Illness?

A way to promote eliminating stigma surrounding mental illnesses is targeting the phenomenon in children. This study's purpose is to validate models of mental illness stigma on children in Grades 6–8. Children completed the revised Attribution Questionnaire in a pretest of a larger study on a mental health education program. Data from this study permitted testing of roles of demographics in these social cognitive models. Subsequent analyses using manifest model structural equations were mixed, but mostly showed adequate fit for multiple versions of the models. These results suggest that models of blame and dangerousness are relevant to the way 10 to 13-year-olds stigmatize mental illness. Demographics were not found to fit these models satisfactorily. Implications of these findings for stigma-change agenda are discussed.     

is affirmative action still necessary?

The influences of socio‐race, racial identity development, gender, educational level, and age on promotion and compensation decisions by midlevel supervisors in industry were examined in this analogue study of 74 midlevel business and industry supervisors. The participants varied in socio‐racial classifications, gender, educational levels, and age. Results of this study indicated statistically significant differences in promotion rates of female analogue employees, rates of promotion between White male and Black male supervisors, and the rate of promotion when comparing older versus younger supervisors.     

Development and Validation of the Weekly Stress Inventory-Short Form

The Weekly Stress Inventory (WSI) has been used both in research and in clinical settings to measure minor stress. Although this tool offers a reliable and valid measure to assess minor stress, it lacks brevity that would make it more feasible for rapid assessments of stress needed in many research and clinical settings. The current study assessed the psychometrics of the newly developed Weekly Stress Inventory Short Form (WSI-SF), a 25-item scale to measure minor stress. Adults attending general medicine clinics (n = 171) at a public teaching hospital completed the WSI-SF and the WSI. The WSI-SF was found to have good internal consistency for both the events score (.92) and impact score (.91) and good convergent validity with the WSI. The results of the present study suggest that the WSI-SF is a reliable and valid instrument for use in assessing minor stress.     

Content Analysis of Suicide Notes as a Test of the Motivational Component of the Existential‐Constructivist Model of Suicide

A sample of 40 suicide notes were analyzed for motivational content in relation to an existential‐constructivist theory of suicide. Results generally supported the 4 theoretical categories of somatic, relational, spiritual, and psychological motivations, with 39 notes having content that could be classified according to the aforementioned categories. Psychological motivations were found to be the most prevalent, followed by relational, spiritual, and somatic concerns. Notes of completed suicides included more relational motivations than did those of suicide attempters, and older writers of notes showed more psychological and fewer spiritual motivations than did younger writers. Recommendations are offered for revising the theory to provide a stronger meaning‐based understanding of suicidal behavior.     

Are dietary restraint scales valid measures of moderate- to long-term dietary restriction? Objective biological and behavioral data suggest not

Prospective studies indicate that elevated scores on dietary restraint scales predict bulimic symptom onset, but experiments indicate that assignment to dietary restriction interventions reduces bulimic symptoms. One possible explanation for the inconsistent findings is that the dietary restraint scales used in the former studies are not valid measures of dietary restriction. The authors previously found that dietary restraint scales were not inversely correlated with objective measures of short-term caloric intake (E. Stice, M. Fisher, & M. R. Lowe, 2004). In this follow-up report, 3 studies indicated that the Three-Factor Eating Questionnaire dietary restraint scale was not correlated with doubly labeled water estimated energy intake over 2-week periods or with observationally measured caloric intake over 3 months. Results from this study and others suggest that dietary restraint scales may not be valid measures of moderate- to long-term dietary restriction and imply the need to reinterpret findings from studies that have used dietary restraint scales.     

Support for hybrid models of the age of acquisition of English nouns

Age of acquisition (AoA) is a psycholinguistic construct that refers to the chronological age at which a given word is acquired. Contemporary theories of AoA have focused on lexical acquisition with respect to either the developing phonological or semantic systems. One way of testing the relative dominance of phonological or semantic contributions is through open-source psycholinguistic databases, whereby AoA may be correlated with other variables (e.g., morphology, semantics, phonology). We report two multiple regression analyses conducted on a corpus of English nouns with, respectively, subjective and objective AoA measures as the dependent variables and a combination of 10 predictors, including 2 semantic, 4 phonological, 2 morphological, and 2 lexical. This multivariate combination of predictors accounted for significant proportions of the variance of AoA in both analyses. We argue that this evidence supports hybrid models of language development that integrate multiple levels of processing—from sound to meaning.     

Efficacy of a program to encourage walking in VA elderly primary care patients: the role of pain

Pain may be a barrier or a negative outcome of initiating and maintaining an exercise program in elderly patients. The purpose of this study was to examine the role of pain in a program designed to increase walking for exercise in 181 veteran primary care patients (60 - 80 years). Self-reported physical activity (min-walked per week) and pain were assessed at baseline, 6, and 12 months. Walking for exercise increased over time without significant changes in pain. Analyses suggested that baseline pain was not a barrier to initiating or maintaining a walking exercise program, nor did increased walking influence reports of pain. These results suggest that patients can be encouraged to engage in physical activity, even if they are currently suffering from pain.     

Searching for Shereshevskii: what is superior about the memory of synaesthetes?

Some individuals with superior memory, such as the mnemonist Shereshevskii (Luria, 1968), are known to have synaesthesia. However, the extent to which superior memory is a general characteristic of synaesthesia is unknown, as is the precise cognitive mechanism by which synaesthesia affects memory. This study demonstrates that synaesthetes tend to report subjectively better than average memory and that these reports are borne out with objective testing. Synaesthetes experiencing colours for words show better memory than matched controls for stimuli that induce synaesthesia (word lists) relative to stimuli that do not (an abstract figure). However, memory advantages are not limited to material that elicits synaesthesia because synaesthetes demonstrate enhanced memory for colour per se (which does not induce a synaesthetic response). Our results suggest that the memory enhancement found in synaesthetes is related to an enhanced retention of colour in both synaesthetic and nonsynaesthetic situations. Furthermore, this may account for the fact that synaesthetic associations, once formed, remain highly consistent.
