The size coding of responses: The size of switches and the force feedback

We aimed to understand which factors have a functional role in the size coding of responses, either the size of the switches or the force required to trigger each switch. This question is of relevance because it allows a better understanding of processes underlying action coding. In each trial, participants saw a small or large object. Depending on its colour, the participants had to press one of two switches. In the “size” condition, the response device consisted of two switches of different visual size, but both required the same amount of force. In the “force-feedback” condition, the response device consisted in two switches of identical visual size, but one switch required more force than the other. We found a compatibility effect in the “size,” not in the “force-feedback” condition, supporting that the size-coding of responses would be due to the size of the switches.     

Memory for emotional faces in major depression following judgement of physical facial characteristics at encoding

The aim of the present study was to establish if patients with major depression (MD) exhibit a memory bias for sad faces, relative to happy and neutral, when the affective element of the faces is not explicitly processed at encoding. To this end, 16 psychiatric out-patients with MD and 18 healthy, never-depressed controls (HC) were presented with a series of emotional faces and were required to identify the gender of the individuals featured in the photographs. Participants were subsequently given a recognition memory test for these faces. At encoding, patients with MD exhibited a non-significant tendency towards slower gender identification (GI) times, relative to HC, for happy faces. However, the GI times of the two groups did not differ for sad or neutral faces. At memory testing, patients with MD did not exhibit the expected memory bias for sad faces. Similarly, HC did not demonstrate enhanced memory for happy faces. Overall, patients with MD were impaired in their memory for the faces relative to the HC. The current findings are consistent with the proposal that mood-congruent memory biases are contingent upon explicit processing of the emotional element of the to-be-remembered material at encoding.     

Type D personality predicts poor medication adherence in myocardial infarction patients

Type D personality, the combination of negative affectivity (NA) and social inhibition (SI), is an emerging risk factor in cardiovascular disease. This study aimed to examine one possible behavioural mechanism to explain the link between Type D and ill-health. It was hypothesised that Type D personality would predict medication adherence in myocardial infarction (MI) patients. In a prospective study, 192 MI patients (54 females and 138 males) completed measures of Type D personality and provided demographic and medical information 1 week post-MI, and then 131 patients went on to complete a self-report measure of medication adherence 3 months post-MI. It was found that Type D personality predicts adherence to medication, after controlling for demographic and clinical risk factors. Critically, the constituent components of Type D, NA and SI, interact to predict medication adherence, after controlling for the effects of each component separately. Poor adherence to medication may represent one mechanism to explain why Type D cardiac patients experience poor clinical outcome, in comparison to non-Type D patients. Interventions, which target the self-management of medication, may be useful in these high-risk patients.     

The impact of assuming the primary caregiver role following traumatic spinal cord injury: An interpretative phenomenological analysis of the spouse's experience

This study aimed to explore the lived experience of assuming the primary caregiver role in a group of spouses of individuals living with a traumatic spinal cord injury (SCI) (injuries ranged from paraplegia to quadriplegia). Individual in-depth interviews were conducted with 11 participants who were both the spouse and primary caregiver of an individual with a SCI; of these, 10 were female and 1 was male. All interviews were transcribed verbatim and were subjected to interpretative phenomenological analysis (IPA). Here we present three inter-related master themes: ‘The emotional impact of SCI’; ‘Post-injury shift in relationship dynamics’ and ‘Impact of caregiving on identity’. Regarding the emotional impact of spinal injury, participants reported an almost instantaneous sense of loss, emptiness and grief during the injured person's rehabilitative period and feelings of anxiety were reported in anticipation of their return to the family home. A distinct change in role from spouse and lover to care provider was reported and this ultimately contributed to relationship change and a loss of former identity. The findings are discussed in relation to extant caregiver literature and recommendations for future caregiver support are highlighted.     

Sensation seeking among high- and low-risk sports participants

Investigated were the sensation seeking tendencies of a diverse sample of 166 athletes. The main aim of the study was to assess empirical support for Zuckermans (1994)Impulsive-Sensation-Seeking (ImpSS) theory and to replicate and extend previous research findings in this area using high- and low-risk sport participants. The Sensation Seeking Scale-V (Zuckerman et al., 1978) and the Impulsiveness Scale of the Impulsiveness-Venturesome-Empathy Scale (Eysenck and Eysenck, 1978), were administered to both male and female athletes currently engaged in one of eight sport disciplines: Hang-gliding, mountaineering, sky-diving, automobile racing, swimming, marathon running, aerobics or golf. Results provided support for the main thrust of Zuckermans ImpSS theory (a) that sensation seeking is integrated within a broader trait called Impulsive-Sensation Seeking; and (b) that total sensation seeking differentiated between high- and low-risk sport participants. On the other hand, these participants did not differ on the impulsiveness dimension. These and other findings are integrated with respect to Zuckermans (1994)Impulsive-Sensation Seeking model. Limitations of the present study and suggestions for future research are also discussed.     

泰文和中文阅读过程中的眼动控制(中文)

This paper analyses some aspects of the eye movement behaviour of readers of Thai and Chinese. The main focus is on readers′landing site distributions on words and how these are affected by the lack of clear word boundary information due to the absence of inter-word spaces. Empirical evidence from Thai and Chinese readers suggest that readers can relatively accurately target word centres. We make the case that this accuracy can be accounted for by a default targetting model(effectively, the prior landing site distribution, in Bayesian terms)modulated by statistical cues about word beginnings available from word-initial character frequencies.     

The role of global top-down factors in local eye-movement control in reading

Although the development of the field of reading has been impressive, there are a number of issues that still require much more attention. One of these concerns the variability of skilled reading within the individual. This paper explores the topic in three ways: (1) it quantifies the extent to which, two factors, the specific reading task (comprehension vs. word verification) and the format of reading material (sentence vs. passage) influence the temporal aspects of reading as expressed in word-viewing durations; (2) it examines whether they also affect visuomotor aspects of eye-movement control; and (3) determine whether they can modulate local lexical processing. The results reveal reading as a dynamic, interactive process involving semi-autonomous modules, with top-down influences clearly evident in the eye-movement record.     

State capacity,economic policy and world system mobility, 1970–1985

Weak states and ineffective economic policies are assumed to mediate the constraints of the world system and to prevent upward mobility among peripheral countries. This article tests the effects of state strength and economic policy on world system mobility in the period 1970–85 on a sample of 162 countries. World system role and mobility were operationalized using role equivalence based network measures. Countries with effective neoorthodox policies experience significantly higher mobility, even after controlling for economic performance, as do countries with states that have high despotic capacity. No effect, direct or indirect, was found for infrastructural state capacity.
