University students’ sleep during an exam period: the role of basic psychological needs and stress

During exam periods university students are at risk for poor sleep. To understand variability in this vulnerability for poor sleep, the role of the satisfaction of the basic psychological needs for autonomy, competence, and relatedness was examined by assessing university students (N?=?121; 78% female; M_age?=?21.69, SD?=?1.39, range 19–25) before, during, and after an exam period. Need-based and sleep-related functioning deteriorated during the exam period and then improved after the exam period. As need satisfaction decreased (i.e., from pre-exam to exam period) sleep quality, sleep quantity and daytime functioning deteriorated, while subsequent increases in need satisfaction (i.e., from exam to the post-exam period) were accompanied by improvements in sleep quality and daytime functioning. These correlated changes in need-based experiences and the sleep-related outcomes were largely accounted for by changes in stress, suggesting that stress may play an explanatory role in these associations.     

Motivation in a MOOC: a probabilistic analysis of online learners’ basic psychological needs

Self-determination theory (SDT) is one of the most well-known approaches to achievement motivation. However, the three basic psychological needs of SDT have not received equivalent attention in the literature: priority has been given to autonomy, followed by the need for competence, with research into relatedness lacking (Bachman and Stewart in Teach Psychol 38: 180–187, 2011. doi: 10.1177/0098628311411798). One new educational setting where relatedness may be particularly important is massive open online courses (MOOCs), which provide unprecedented opportunities for either relatedness or isolation. The purpose of the research was to use Bayesian networks (BN) to establish probabilistic relationships between learners’ basic psychological needs in the context of one MOOC. The majority (59 %) of participants (N = 1037; 50 % female and 50 % male) were under 45 (age range was 18–74 years). This sample represented approximately 88 regions and countries. Participants completed a revised Basic Student Needs Scale (Betoret and Artiga in Electron J Res Educ Psychol 9(2): 463–496, 2011). In order to reveal the best structural understanding of SDT within a MOOC learning environment, analysis of the data involved the development of a BN probabilistic model. The best fitting BN model included autonomy, competence, and relatedness—resulting in a probabilistic accuracy of 77.41 %. Analyses revealed participants with high autonomy had an 80.01 % probability of having a moderate level of competence. Relatedness was distinct from the autonomy and competence relationship. The strong inter-connections between autonomy and competence support existing research. The notion that relatedness may be a distinct need, at least in this context, was supported and warrants future research.     

Recognizing one’s own clapping: The role of temporal cues

Do individuals recognize their own clapping? We investigated this question with an off-line paradigm in which the perception of the claps is temporally separated from their generation. In a first experiment, we demonstrated that acoustic recordings of clapping provide sufficient information for discriminating between one’s own performance and that of another participant. Self-recognition was still preserved when the claps were reproduced by uniform tones that only retained their temporal pattern. In a subsequent experiment, we verified that the general tempo provides an important cue for self-recognition. Finally, we showed that self-recognition does not rely on concurrent synchronization of actual movements with the auditory sequences. The results are discussed in the light of current theories about perception-action links.     

What is satisfying about satisfying events? Testing 10 candidate psychological needs

Three studies compared 10 candidate psychological needs in an attempt to determine which are truly most fundamental for humans. Participants described "most satisfying events" within their lives and then rated the salience of each of the 10 candidate needs within these events. Supporting self-determination theory postulates (Ryan & Deci, 2000)--autonomy, competence, and relatedness, were consistently among the top 4 needs, in terms of both their salience and their association with event-related affect. Self-esteem was also important, whereas self-actualization or meaning, physical thriving, popularity or influence, and money-luxury were less important. This basic pattern emerged within three different time frames and within both U.S. and South Korean samples and also within a final study that asked, "What's unsatisfying about unsatisfying events?" Implications for hierarchical theories of needs are discussed.     

Does organizational reciprocity improve employees’ motivation? The mediating role of basic psychological need satisfaction

The psychological side of Hempel’s paradox of confirmation

People often test hypotheses about two variables (X andY), each with two levels (e.g.,X1 andX2). When testing “IfX1, thenY1,” observing the conjunction ofX1 andY1 is overwhelmingly perceived as more supportive than observing the conjunction ofX2 andY2, although both observations support the hypothesis. Normatively, theX2&Y2 observation provides stronger support than theX1&Y1 observation if the former is rarer. Because participants in laboratory settings typically test hypotheses they are unfamiliar with, previous research has not examined whether participants are sensitive to the rarity of observations. The experiment reported here showed that participants were sensitive to rarity, even judging a rareX2&Y2 observation more supportive than a commonX1&Y1 observation under certain conditions. Furthermore, participants’ default strategy of judgingX1&Y1 observations more informative might be generally adaptive because hypotheses usually regard rare events.     

The role of parents’ autonomy support and psychological control in sibling relationship functioning through children’s need-based experiences

This study aimed to examine whether parents’ autonomy support and psychological control during sibling conflict would relate to children’s need-based experiences and relationship functioning within the sibling relationship. Two siblings (M_age = 8.61 years, SD = 0.91 and M_age = 10.50 years, SD = 0.94) of 205 families filled out questionnaires. Results showed that parental autonomy support related positively to siblings’ relationship satisfaction via children’s need satisfaction. Additionally, fathers’ psychological control related negatively to provided autonomy support and positively to provided psychological control from one sibling to the other (as reported by the other sibling) and negatively to satisfaction with this relationship via need frustration. These findings highlight the importance of the quality of parents’ involvement during sibling conflict.     

Impulse control disorders in Parkinson’s disease: Predominant role of psychological determinants

Objectives: Impulse Control Disorders (ICDs) in Parkinson’s disease (PD) have previously almost exclusively been considered to result from anti-parkinsonian medication. However, this biomedical perspective has failed to achieve a full understanding of the phenomenon and it is argued that a failure to consider psychological factors is a critical omission.

Design: The present study examined the predictive relationship between ICDs in PD and a range of psychological measures, whilst controlling for a number of biomedical determinants.

Main outcome measures: One hundred participants with idiopathic PD completed questionnaires that assessed demographic and clinical characteristics, psychological measures and the presence of ICDs (QUIP-RS).

Results: Increased use of a ‘negative’ coping strategy, stronger illness identity, more emotional illness representations and stress were found to be significant predictors of ICDs, and different psychological predictors were associated with different ICDs. Medication was not found to predict ICDs in the presence of psychological factors, either when total treatment levels were considered or when agonist dose was considered alone.

Conclusions: This study provides the first quantitative evidence of a predominant predictive relationship between psychological factors and ICDs in PD. The results suggest that psychological interventions may have useful therapeutic role to play for ICDs in PD.     

The twofold role of diagrams in Euclid’s plane geometry

Proposition I.1 is, by far, the most popular example used to justify the thesis that many of Euclid??s geometric arguments are diagram-based. Many scholars have recently articulated this thesis in different ways and argued for it. My purpose is to reformulate it in a quite general way, by describing what I take to be the twofold role that diagrams play in Euclid??s plane geometry (EPG). Euclid??s arguments are object-dependent. They are about geometric objects. Hence, they cannot be diagram-based unless diagrams are supposed to have an appropriate relation with these objects. I take this relation to be a quite peculiar sort of representation. Its peculiarity depends on the two following claims that I shall argue for: (i) The identity conditions of EPG objects are provided by the identity conditions of the diagrams that represent them; (ii) EPG objects inherit some properties and relations from these diagrams.     

The syllable’s role in word naming

In a series of experiments, the masked priming paradigm with very brief prime exposures was used to investigate the role of the syllable in the production of English. Experiment 1 (word naming task) showed a syllable priming effect for English words with clear initial syllable boundaries (such as BALCONY), but no effect with ambisyllabic words targets (such as BALANCE, where the /l/ belongs to both the first and the second syllables). Experiment 2 failed to show such syllable priming effects in the lexical decision task. Experiment 3 demonstrated that for words with clear initial syllable boundaries, naming latencies were faster only when primes formed the first syllable of the target, in comparison with a neutral condition. Experiment 4 showed that the two possible initial syllables of ambisyllabic words facilitated word naming to the same extent, in comparison with the neutral condition. Finally, Experiment 5 demonstrated that the syllable priming effect obtained for CV words with clear initial syllable boundaries (such as DIVORCE) was not due to increased phonological and/or orthographic overlap. These results, showing that the syllable constitutes a unit of speech production in English, are discussed in relation to the model of phonological and phonetic encoding proposed by Levelt and Wheeldon (1994).     

The role of inhibition in young children’s altruistic behaviour

By behaving altruistically, individuals voluntarily reduce their benefits in order to increase their partners’. This deviation from a self-interest-maximizing function may be cognitively demanding, though. This study investigates whether altruistic sharing in 4- to 6-year-old children, assessed by a dictator game (DG), is related to three measures of executive functioning, that is, inhibitory control, working memory, and cognitive flexibility. We found that children who turned out to be altruistic in the DG performed better on an inhibition task than non-altruists did. This finding lends support to the hypothesis that altruistic sharing might be somewhat constrained by the child’s ability to inhibit a natural tendency to preserve his or her own resources. Much research is needed to understand the role of inhibitory control in the development of costly sharing and the consolidation of inequity aversion.     

One role or two? The function of psychological separation in role conflict

Student athletes vary in how much they view their academic and athletic role identities as separate from and interfering with each other. The authors investigated the relation of these perceptions to psychological well-being in 200 intercollegiate athletes. Measures included role separation, interference, identity, and well-being. Correlations indicated that interference related negatively to well-being, whereas viewing the roles as distinct related positively to well-being. Regression analyses of demographic and role identity variables also showed a positive association between role separation and well-being, and a significant Separation x Interference interaction. Specifically, role interference was negatively related to well-being for those who viewed the two roles as distinct but unrelated for those who did not. The buffering effects of role separation are discussed.     

The physician’s role in the protection of human research subjects

Responsibility for the protection of human research subjects is shared by investigators, research ethics committees, sponsors/funders, research institutions, governments and, the focus of this article, physicians who enrol patients in clinical trials. The article describes the general principles of the patient-physician relationship that should regulate the participation of physicians in clinical trials and proposes guidelines for determining when and how such participation should proceed. The guidelines deal with the following stages of the trial: when first considering participation, when deciding whether to enrol patients, when asking patients to participate, when the trial is underway and when it is completed.     

The role of gradients of binocular disparity in Gibson’s theory of space perception

Adult Ss made distance bisection judgments over a surface on which the packing density of the texture elements was progressively increased along the Ss’ line of sight from one end of the surface to the other. Distance judgments were significantly different under monocular and binocular conditions of vision; however, with binocular vision, Ss did not detect the deformation in the texture on the surface. This result does not support predictions derived from Gibson, Purdy, and Lawrence (1955) concerning the role of gradients of binocular disparity in Gibson’s psychophysical theory of space perception.     

The role of social support in women’s health and recovery processes

The aim of this study was to assess the psychological state of women who have undergone surgery for breast cancer or cardiac surgery, including examination of the role of social support in both groups. The study included 48 women (mean age: 66.04?±?8.3 years). They were divided into two groups according to diagnosis: 23 women (mean age: 69.2?±?8.6 years) who underwent heart surgery (cardiac group, CG) and 25 women (mean age: 63.2?±?7.0 years) treated for breast cancer and associated with the Women After Mastectomy Club (oncology group, OG). In addition to the assessment of socio-demographic variables, the following self-report questionnaires were administered: Satisfaction with Life Scale, Acceptance of Illness Scale, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory as well as Berlin Social Support Scale. In the CG, the severity of depressive symptoms was two times higher than in OG (p?=?.003). In both groups, there was a high percentage (80%) of women with severe symptoms of anxiety (p?=?.37). In both groups, the level of life satisfaction was similar (p?=?.58), but OG was characterized by a higher level of acceptance of the disease (p?=?.003). The correlation analysis showed that in both groups, social support was related differently to the parameters of emotional state. Women treated for breast cancer were in a better mental condition than women treated for heart disease. The support coming from other women in similar circumstances (Women After Mastectomy Club) seems to be more effective than the support coming from the patient’s immediate environment. The results for social support ought to be interpreted not only through the prism of mean values of received support, but also with regard to the information on the sources of support.     

Psychotherapists’ psychological well-being: The role of epistemic orientation and emotion regulation

Psychotherapists’ mental health has been traditionally associated with the harmful consequences of clinical practice. In contrast to this dominant model, a growing body of research in positive psychology has sparked an interest in therapists’ positive well-being. The main objective of this study was to examine the relations between therapists’ epistemic orientation modes, emotion regulation strategies and psychological well-being (PWB). This was a cross-sectional study in which participants were 674 therapists (78.5% women), with a mean age of 42.02 years (SD = 13.06). Therapists completed an online questionnaire containing self-report measures of all study variables. Structural equation modelling using latent variables was performed to test the study hypotheses. Results revealed no significant direct effects of epistemic orientation on PWB. Up- and downregulation strategies had the most substantial direct effects on total PWB. Furthermore, emotion regulation mediated the association between therapists’ epistemic orientation modes and PWB, accounting for 57% of the variance in the outcome variable. Implications for training, practice and therapist self-care are discussed.     

The role of ability in creative ‘incubation’

While many people report interruptions from problem-solving to be beneficial for the creative process (‘incubation’), experimental demonstration of the phenomenon has been difficult. Factors that might lead to incubation effects are discussed and implemented in a study in which 80 university students solved word-association problems under continous work or interrupted conditions. The interruptions involved work on other problems, other problems plus periods of conversation or other problems plus work on an unrelated mental rotation task. The results showed the incubation phenomenon in one condition and, most importantly, the ability level of the Ss for the task involved determined whether incubation would occur. High-ability Ss benefited from the interruptioninvolving the rotations task, while low-ability Ss did not show any incubation effects. Comparisons to previous studies and suggestions for future research are made throughout.     

The role of entrenchment in children’s and adults’ performance on grammaticality judgment tasks

Between the ages of 3 and 7 years, children have been observed to produce verb argument structure overgeneralization errors (e.g., Don’t giggle me; Bowerman, 1982, 1988; Pinker, 1989). A number of recent studies have begun to find evidence that the precise distributional properties of the input may provide an important part of the explanation for why children retreat from overgeneralization errors (Brooks & Tomasello, 1999; Brooks, Tomasello, Dodson, & Lewis, 1999). The current study evaluates the role of entrenchment (Braine & Brooks, 1995) in constraining argument structure overgeneralization errors using a grammaticality judgment task. The 5-year-olds, 8-year-olds, and adults were presented with examples of argument structure errors containing high and low frequency verbs matched for semantic class and asked to indicate whether, or the extent to which they found the sentences to be grammatical. The data show that across all groups, sentences with argument structure errors containing low frequency verbs were judged to be significantly more grammatical than those containing high frequency verbs. These findings provide further support for the entrenchment hypothesis and suggest that verb frequency plays an important and continuing role in determining a speaker’s choice of verb argument structure.
