The role of gaze and road edge information during high-speed locomotion

Robust control of skilled actions requires the flexible combination of multiple sources of information. Here we examined the role of gaze during high-speed locomotor steering and in particular the role of feedback from the visible road edges. Participants were required to maintain one of three lateral positions on the road when one or both edges were degraded (either by fading or removing them). Steering became increasingly impaired as road edge information was degraded, with gaze being predominantly directed toward the required road position. When either of the road edges were removed, we observed systematic shifts in steering and gaze direction dependent upon both the required road position and the visible edge. A second experiment required fixation on the road center or beyond the road edges. The results showed that the direction of gaze led to predictable steering biases, which increased as road edge information became degraded. A new steering model demonstrates that the direction of gaze and both road edges influence steering in a manner consistent with the flexible weighted combination of near road feedback information and prospective gaze information.     

Patterns of choices on video game genres and Internet addiction

In this study, we attempt to identify motives pivotal in choices made regarding online and offline game genres and assess whether they are meaningful predictors of Internet addiction. A separate goal was to determine how an assessment of Internet-related cognitions compares to criteria-based research instruments on Internet addiction, and demonstrate its clinical usefulness. We are using data from a cross-sectional study of the entire adolescent student population aged 12-18 of the island of Kos. Results indicate that specific game genres and motives for choosing a game are important predictors of Internet addiction, even after accounting for sociodemographic and Internet-use-related variables. Gender differences are not statistically important when we account for genre choices and motives for choosing them. Boys' thought content tends to revolve more around their Internet use compared to girls. Several patterns of motives to play specific genres were identified with the help of a canonical correlation analysis, demonstrating the fact that the simple observation of overt behavior is not enough to deduce the meaning of these actions for the individual. Using multiple measures of online addiction, examining genre preferences and underlying motives for choosing a game can be helpful in reaching a better understanding of the individual game player.     

Personality factors associated with psychological distress in testicular cancer survivors

The aim of this study was to investigate symptoms of anxiety and depression in testicular cancer survivors (TCSs) and to identify personality traits associated with psychological distress in these patients by means of the MMPI (Hathaway & McKinley, 1943). A total of 50 TCSs and 50 age-adjusted healthy men participated in the study, and we used the following self-report instruments: Montgomery-Asberg Depression Rating Scale (Montgomery & Asberg, 1979), Hamilton Anxiety Rating Scale (Hamilton, 1959, 1969), Spielberger's State-Trait Anxiety Inventory (Spielberger, 1970, 2005), and the MMPI. TCSs displayed higher rates on all psychopathology scales studied compared to controls, but the majority of the patients' scores were within the "normal range," indicating rather mild psychological distress. TCSs' MMPI profiles showed higher rates on Scales 1, 3, 6, and 9 compared to controls; and within the TCSs sample, symptoms of depression were most closely associated with Scales 3 and 5. Similarly, anxiety symptoms were mainly associated with Scale 3. These findings indicate that TCSs present mild symptoms of psychological distress, mainly anxiety and depressive symptoms, suggesting that careful assessment and consultation in TC patients is essential to help them deal with distress after treatment and to minimize possible risk factors.     

Anxiety and depression in Greek nursing and medical personnel

The relatively low number of nurses compared to physicians in Greece and the few available studies on the psychological problems of the health professionals led to comparison of anxiety and depression for 76 Greek nursing personnel (20 men, M age: 32.8 yr., SD: 3.8 yr., and 56 women, M age: 36.6 yr., SD: 7.7 yr.) and 66 doctors (35 men, M age: 35.9 yr., SD: 8.9 yr. and 31 women, M age: 32.7 yr., SD: 8.1 yr.) using validated translations of the Spielberger State-Trait Anxiety Inventory and the Beck Depression Inventory. Male nurses had the lowest scores on trait anxiety, while female doctors had the highest scores, followed by female nurses. Depression scores were not different between doctors and nurses, regardless of sex. Age and depression scores were positively correlated (Spearman rho = .31) only for the female nurses. The findings suggest that interventions for diagnosis and stress management in the health-care workplace should be equally targeted for nursing and medical personnel.     

The effect of group psychological counselling in Greek university students’ anxiety,depression, and self-esteem

Objective: During the last decades there has been a marked increase in both the number of students with severe psychological problems on campus and the number of students seeking counselling services. The present study measured the effect of a group psychological counselling program on university students’ anxiety, depression, and self-esteem. Design: Data were derived from six separate groups and a total of 53 participants (19 male, 34 female). The intervention was based on Cognitive-Behavioural Group Therapy (CBGT) and included cognitive and behavioural techniques in eight, two-hour weekly sessions. The quasi-experimental longitudinal study used a pretest/posttest group design. The participants completed the Spielberger's State–Trait Anxiety Inventory (STAI), the Beck Depression Inventory (BDI), and the Rosenberg Self-esteem Scale (RSE) before and after the intervention. Data were analyzed using t-tests. Results: The results indicated the existence of meaningful differences in terms of state and trait anxiety, depression and self-esteem from pre-treatment to post-treatment. Conclusion: The program was effective in decreasing significantly participants’ anxiety and depressive symptoms, as well as increasing their self-esteem. These are encouraging results demonstrating an effective form of the intervention on student population.     

Plotinus: towards an ontology of likeness (On the One and Nous)

Plotinus’ thesis of the relationship between the One and Nous (Intellect) is central to his thought. In dealing with this relationship, he concentrates far more on what makes the One and Nous alike than on what makes them different. This is because by preference he envisages the One as the ‘causal principle () of everything’, in what might be termed a ‘top‐down’ model of metaphysics in which first cause (the One) leads downwards to second cause (Nous). Plotinus is obliged to present the distinction between the One and Nous as relative, not as absolute, precisely because he wants to show that Nous is firmly grounded in the One. The One differs from Nous to no more than the degree, and in no more than the manner, that are necessary for there to be created a Nous which is as like as possible to the One Itself.     

Context effects in marketing practice: the case of mood

The role of individuals' affective state on information processing and decision making has attracted the attention of researchers in the social sciences. Building on the findings reported in the literature, the authors examine the effects of mood on marketing practice. Implications for advertising practices as well as the potential manipulation of elements of the physical store/retail environment (atmospherics) in which consumers operate in order to affect behaviour are discussed.

Sense of Coherence (SOC) in Christian Orthodox Monks and Nuns in Greece

This paper aims to investigate the stress management skills of Christian Orthodox monks and nuns, as measured by Antonovsky’s scale sense of coherence (SOC). A case–control study was designed to test the hypotheses whether monks and nuns have higher SOC than secular people. The study population consisted of 193 individuals, 96 monks and nuns (study group) and 97 secular men and women (control group). SOC score was higher in monks and nuns as compared to the secular population (p = 0.002), men as compared to women (p = 0.012) and persons of older age (p = 0.004) as compared to younger individuals.
