Measuring the Ability to Express Sexual Thoughts

Ratings were obtained from 30 male college students as to the sexual stimulus relevance of a number of pictures from magazines, each depicting a man and a woman. Then a different group of 72 male students were asked to tell stories about the situations depicted in pictures representing 4 levels of rated sexual stimulus relevance. Half were given ambiguous instructions, while the other half were instructed to tell sexy stories. In general, sexier pictures elicited sexier stories, the effect being more marked with ambiguous instructions. Sexy instructions led to sexier stories except at the highest level of stimulus relevance. The results were interpreted within the framework of an abilities conception of personality.     

Overlooking the Obvious: Incentives to Lie

Over the years, people have searched for deception cues in the liar's behavior. However, the sender's incentives to lie might be more revealing than behavior. In Experiment 1, an incentive was developed that was predictive of lying. Judges with access to incentive information in addition to behavior achieved almost perfect lie/truth detection. This was not a result of the speakers' behavior being transparent (Experiment 2) but because incentive information was useful to separate lies from truths (Experiments 2 and 3). Experiment 3 revealed that people may forego perfectly diagnostic contextual cues to base their judgments on illusory behavioral cues.     

Emergent Motivation to Read in Prekindergarten Children

This study aimed to develop and validate a measure of emergent reading motivation designed for prekindergarten children, called the Emergent Reading Motivation Scale (ERMS). The development of the ERMS was to overcome the limitation that current existing reading motivation measures are not developmentally appropriate for young children. Fifty-six native-English speaking children who were enrolled in a prekindergarten program participated in the study. The ERMS had 17 items that were drawn from reading self-concept, reading performance goal, and reading learning goal. The scale was administered through two sock puppets. For each item, the puppets represented contrasting behaviors regarding reading motivation. The children were asked to choose the puppet that was most like themselves. Results suggested that the ERMS is an age-appropriate reading motivation measure for prekindergarten children and has a three-factor structure as assumed even though its internal consistency is moderate and is of limited predictive power of emergent literacy skills.     

The Validity of Receptive and Expressive Vocabulary Measures with Spanish-Speaking Kindergarteners Learning English

Research examined construct meaning and validity for two new measures of receptive and expressive vocabulary for Spanish-speaking kindergarteners learning English. Substantive validity and generalizability of score meaning was assessed by examining correlations between an established measure (Peabody Picture Vocabulary Test–PPVT) and new measures (Stanford English Language Proficiency Test–SELP; Dynamic Indicators of Basic Early Literacy Skills, Word Use Fluency, DIBELS–WUF). Positive correlations between the SELP and PPVT supported validity of the SELP as a measure of receptive and expressive vocabulary for these children. DIBELS–WUF results were less clear with lower correlations between the PPVT raising questions about appropriateness.     

Examining Spouse/Partner Presence as a Moderator in the Relationship Between Mental Health Symptoms and Alcohol Use in OEF/OIF Veterans

Veterans from the conflicts in Afghanistan (Operation Enduring Freedom; OEF) and Iraq (Operation Iraqi Freedom; OIF) have reported elevated rates of alcohol consumption, and greater depression and posttraumatic stress disorder (PTSD) symptoms are associated with increased alcohol use. Presence of a spouse/partner, which has been associated with reduced drinking, may buffer the relationship between mental health symptoms and alcohol consumption. To examine this hypothesis, the current study utilized baseline survey data from OEF/OIF veterans (N = 325) enrolled in a brief alcohol intervention. Spouse/partner presence moderated the relationship between depression symptoms and alcohol consumption such that depression was positively associated with drinking for veterans without a spouse/partner. Exploratory analyses indicated that the relationship between depression and alcohol use may be particularly salient for veterans without a spouse/partner and a lower number of deployments. Spouse/partner presence did not moderate the relationship between PTSD symptoms and alcohol consumption. Implications of the findings are discussed.     

The relationship between mental vitality and cardiovascular health

Past measurement of vitality has included both emotional and physical components. Since aspects of physical vitality such as fatigue can be indicative of physical illness, the usefulness of existing measures of vitality to predict health is limited. This research was designed to examine the psychometric properties of a new Mental Vitality Scale and to test its associations with measures of cardiovascular health over the course of 2 years. The measure of mental vitality was administered in a two-part study using three different samples. In part 1, the reliability and validity of the scale was assessed with a student and a clinic sample. In part 2, medical data on mental and physical health were abstracted over a two-year period from 1041 patient records from a multi-specialty medical practice, and mental vitality assessed through a mailed questionnaire. The findings indicate that the Mental Vitality Scale is a valid and reliable questionnaire for measuring this construct. Mental vitality was also associated with reduced odds of several cardiovascular outcomes and prospective analyses suggest that mental vitality may serve a protective function in the development of cardiovascular disease. The results lend support for the importance of mental vitality as a construct that may be relevant for considering resilience in relation to cardiovascular disease.     

Strength of hand preference and dual task performance by common marmosets

Study of avian and piscine species has shown that animals with stronger lateralization of the brain are able to perform two tasks presented simultaneously better than can animals with weaker lateralization. We investigated whether this might apply also to primates by testing common marmosets to see whether there is a relationship between the strength of hand preference, as an indicator of strength of brain lateralization, and the ability to carry out two tasks simultaneously. A model predator was introduced into the testing room while the marmoset was foraging. Marmosets with stronger hand preferences detected the ‘predator’ after shorter latency than those with weaker hand preferences. Furthermore, the marmosets with stronger hand preferences produced more mobbing (tsik) vocalizations when they reacted to the predators than did those with weaker hand preferences. There was no such association between hand preference and either latency to respond to the predator or mobbing reaction when the marmosets were not foraging at the time the predator was introduced. Hence, strength of lateralization is associated with the ability to perform foraging and predator detection simultaneously. These results are discussed with reference to the evolution of brain lateralization.     

Cue competition effects in the planarian

The learning abilities of planarian worms (Dugesia tigrina) were assessed by using a number of Pavlovian conditioning paradigms. Experiment 1 showed that planaria were susceptible to basic conditioning in that they readily developed a conditioned response to a change in ambient luminance when it was consistently paired with an electric shock over a number of trials. In Experiment 2, the change in luminance was presented in a compound with a vibration stimulus during conditioning. Subsequent tests revealed poor conditioning of the elements compared with control groups in which the animals were conditioned in the presence of the elements alone, an instance of overshadowing. In Experiment 3, pre-training of one of the elements before compound conditioning resulted in blocking of learning about the other element. These results add to other studies that have reported cue competition effects in animal species belonging to different phyla (chordate, mollusk, arthropod), suggesting that learning in these phyla could be ruled by similar principles. The results are discussed adopting an evolutionary-comparative approach.     

Women Experiencing Psychological Abuse: Are They a Homogenous Group?

Dichotomizing women as “abused” versus “not abused” assumes that any psychological maltreatment results in similar outcomes. A national sample of women in conflictual relationships completed an online survey. Women with no incidence (N = 33), the lowest quartile (N = 86), and the top quartile (N = 81) of psychological maltreatment demonstrated significant differences in reactions to the maltreatment, mental health indicators, personality variables, perceived harm, problematic relationship schemas, and response styles. Women with no psychological abuse and women in the lowest quartile produced similar scores that were typically distinct from the top-quartile women. Effective treatment of women with lower amounts of psychological abuse might not require a unique intervention likely necessary for women experiencing much psychological abuse.
