Digit ratio (2D:4D) and aggregate personality scores across nations: Data from the BBC internet study

The purpose of this study was to consider relationships between digit ratio (2D:4D, a putative correlate of prenatal sex steroids) and aggregate personality scores across nations. Differences in national personality scores may be influenced by such factors as prevalence of the parasite Toxoplasma gondii, latitude and economics, and variation in 2D:4D has also been linked to prevalence of T. gondii and to latitude. Here we report associations of mean 2D:4D per country and latitude, gross domestic product (GDP), T. gondii prevalence and personality profiles in 23 nations of an internet study. 2D:4D was not related to latitude or to T. gondii, but was related to GDP (women only). With regard to national personality scores, 2D:4D was not related to masculinity but there were significant positive relationships of 2D:4D with uncertainty avoidance in men and women and with neuroticism in men. Male 2D:4D was significantly related to uncertainty avoidance and neuroticism independent of T. gondii, whereas female 2D:4D was not significantly related to uncertainty avoidance or neuroticism after controlling for the effect of T. gondii and GDP. We conclude that nations with high male 2D:4D (low prenatal testosterone, high prenatal oestrogen) have high scores for uncertainty avoidance and neuroticism.     

Depression and medication adherence among breast cancer survivors: bridging the gap with the theory of planned behaviour

Evidence suggests that more depressed breast cancer patients will less likely adhere to treatment plans. This study presents evidence that the theory of planned behaviour mediates the relation between depression and intentions to adhere to treatment plans and between depression and lack of adherence to medication regime. Two hundred and thirteen women undergoing breast cancer treatment participated in this study. Measures of depressive symptoms and planned behaviour variables were collected at the first time point; measures of medication adherence were collected at the second time point. Structural equation models were utilised to fit the data to the proposed models. Depressive symptoms were significantly correlated to both intentions and medication adherence. In support of hypotheses, the relation between depressive symptoms and treatment intention was mediated by attitudes towards health maintenance plans. The relation between depressive symptoms and medication adherence was fully mediated by the planned behaviour process. Conditions under which treatment intentions and perceptions of control in adhering to treatment were most related to medication adherence were elucidated. The results point to avenues for interventions to increase medication adherence among breast cancer patients. Manipulating attitudes and perceptions of control towards treatment plans will potentially serve to increase medication adherence.     

Response effects of equated values of event frequency, repetition, and alternation in one-and two-cue probability learning

An experiment using 50 college students equated cue values of frequency, repetition, and alternation in one- and two-cue partially random sequences in order to determine whether the cues were responded to independently or in combination and to test earlier results concerning cue saliency. Using improved methods of data analysis, previous findings that repetition is more salient than frequency and frequency more salient than alternation were replicated. In spite of the saliency differences, the design employed demonstrated that both cues in two-cue sequences were responded to and that responses to one-cue appeared to be independent of responses to the other.     

Enduring as Lived Experience: Exploring the Essence of Spiritual Resilience for Women in Late Life

The purpose of this study was to explore spirituality and its relationship to resilience for women in late life. Over thirty interviews with six women aged 80 and older provide a dataset allowing for the phenomenological investigation of spiritual resilience. Themes emerged illustrating the components of spiritual resilience. The components of spiritual resilience are having divine support, maintaining purpose, and expressing gratitude. These factors are essential to the women’s resilience and act as mechanisms that promote high levels of subjective well-being and an overall good quality of life. Essentially, participants articulate how their experiences of enduring hardships are informed by spiritual resilience.     

Effects of visual and tactual stimulus presentation on learning two-choice patterned and semirandom sequences.

Three experiments compared the effects of visual and tactual stimulus presentation in two-choice sequential learning situations requiring a predictive response. In Experiments 1 and 2, subjects received a five- or six-unit repeating pattern; in Experiment 3, they received a semirandom sequence. Tactual as compared to visual stimulus presentation resulted in less trials to criterion in predicting a repearing pattern and in earlier frequency matching in predicting a semirandom sequence. These results suggest an unusual tactual adeptness in binary serial learning. Additionally, a new method of analyzing conditional responding in th brobability learning paradigm is described and applied to the data in Experiment 3.     

Are Children's Concerns About Punishment Related to Their Aggression?

Although moral reasoning is recognized as an influence on students' behavior, it is often overlooked in policies and interventions developed to change their behavior. Relations between specific types of moral reasoning (i.e., imminent, probable, physical, and psychological) and teacher-reported overt aggression were examined in 203 first and second graders. Regression analyses indicated that psychological reasoning explained a significant amount of the variance in overt aggression. Follow-up analyses indicated that overtly aggressive boys demonstrated more concern for the imminent consequences of their behavior on themselves (e.g., punishment) and less concern for the psychological consequences of their actions on others (e.g., hurting others' feelings) than nonaggressive boys. Implications for the prevention and treatment of aggressive behavior are discussed.     

When mitigation evidence makes a difference: effects of psychological mitigating evidence on sentencing decisions in capital trials

Little empirical research has addressed the effects of psychological or psychosocial evidence on sentencing decisions. The present study found that death-qualified mock jurors were more likely to sentence a defendant to death without mitigating evidence than in a case with mitigating evidence present. Mock jurors were less likely to assign a death sentence in cases that contained one of the following types of mitigating evidence: The defendant was (i) diagnosed with schizophrenia, not medicated, and suffered from severe delusions and hallucinations, (ii) drug addicted and high at the time of the murder, (iii) diagnosed as borderline mentally retarded during childhood, or (iv) severely physically and verbally abused by his parents during childhood.     

Interpreting semantic clustering effects in free recall

The order in which participants choose to recall words from a studied list of randomly selected words provides insights into how memories of the words are represented, organised, and retrieved. One pervasive finding is that when a pair of semantically related words (e.g., "cat" and "dog") is embedded in the studied list, the related words are often recalled successively. This tendency to successively recall semantically related words is termed semantic clustering (Bousfield, 1953; Bousfield & Sedgewick, 1944; Cofer, Bruce, & Reicher, 1966). Measuring semantic clustering effects requires making assumptions about which words participants consider to be similar in meaning. However, it is often difficult to gain insights into individual participants' internal semantic models, and for this reason researchers typically rely on standardised semantic similarity metrics. Here we use simulations to gain insights into the expected magnitudes of semantic clustering effects given systematic differences between participants' internal similarity models and the similarity metric used to quantify the degree of semantic clustering. Our results provide a number of useful insights into the interpretation of semantic clustering effects in free recall.
