New York Prophecies: The Imaginary Future of Artificial Intelligence

The conflicts which have erupted over hacking, cracking and filesharing offer a stepping-stone for rethinking the involvement of users in innovation processes. As technical design processes invariably proceed in the shadow of established relations of social power, we can expect them to encompass conflicts over what constitutes the creative use of technology versus its misuse. The figure of the misuser calls attention to the importance of antagonistic relations in the mutual shaping of technology and society. Constructivist STS research has been criticised for neglecting the importance of antagonistic relations in favour of an emphasis on the limitless mutability of human/machine hybrids. The transformative effects of innovation processes on interests and subjectivities cannot be denied. But the induction of such transformations might be interpreted as a method through which struggles are conducted. This dynamic is particularly forthcoming in the case of filesharing, where users innovate precisely in order to overthrow the material practices upon which intellectual property law is founded. It is the intervention of law enforcement agencies in the process of drawing the line between users and misusers that makes the presence of an antagonistic relation manifest.     

Remembering talk: Individual and gender differences in reported speech

This study examined individual and group differences in the nature and frequency of reports of past speech in the autobiographical memories of young adults. A sample of 108 participants (60 females, 48 males) responded in writing to six memory prompts. They also completed the Five Factor Inventory (Costa & McCrae, 1992) and the Personal Attributes Questionnaire (Spence & Helmreich, 1978). The frequency with which participants used reported speech was correlated with agreeableness, openness, and expressivity; however, regression analyses indicated that narrators’ gender alone was the best predictor. Females used more reported speech than did males. The findings suggest that recollections of past speech are an under-appreciated yet important component of autobiographical memory.     

Comparing two perceived characteristics of autobiographical memory: Memory detail and accessibility

Four samples of participants recalled autobiographical memories. While some evidence emerged from regression analyses suggesting that judgements of the amount of detail contained in each memory and judgements of the ease with which events could be recalled were partially independent, the analyses generally showed that these judgements were similarly predicted by various event characteristics (age, typicality, self-importance, emotional intensity at event occurrence, rehearsal types). Co-occurrence frequency data yielded similar conclusions, showing that while ease ratings and detail ratings occasionally diverged, they were more often consistent with each other. Finally, the data also suggested that events that prompted emotional ambivalence were not judged to be more easily recalled, or to contain more detail, than non-ambivalent events.     

Phenomenology of autobiographical memories: The Memory Experiences Questionnaire

The phenomenology of autobiographical memories varies on a number of dimensions: some memories are vivid and others dim; some are emotionally intense and others lack emotional content. The present research sought to develop a psychometrically-sound scale to assess the entire range of dimensions on which autobiographical memories differ. We reviewed the literature on memory experiences and identified 10 relevant dimensions: Vividness, Coherence, Accessibility, Time Perspective, Sensory Details, Visual Perspective, Emotional Intensity, Sharing, Distancing, and Valence. We constructed a comprehensive item pool to assess these dimensions and, using data from several large samples (Ns=941; 510; 212), we showed that: (a) all 10 scales had adequate reliability (median alpha=.87; range=.72 to .97), (b) the 10-factor structure provided a good fit to the data, and (c) gender, personality, and memory recency had theoretically meaningful relations with the 10 scales. For example, gender and ethnicity differences in phenomenology were mediated by memory content, and early and recent memories had distinct phenomenologies. The discussion focuses on the theoretical and practical utility of the 10 scales.     

Examining the long-term stability of overgeneral autobiographical memory

Overgeneral autobiographical memory (OGM) is a proposed trait-marker for vulnerability to depression, but relatively little work has examined its long-term stability. This study investigated the stability of OGM over several years in 271 late adolescents and young adults participating in a larger longitudinal study of risk for emotional disorders. The Autobiographical Memory Test (AMT) was administered twice, with test–retest intervals ranging from approximately 3 to 6 years. There was evidence of significant but modest stability in OGM over several years. Specifically, Spearman rank correlations (ρs) between the proportions of specific and categoric memories generated on the two AMTs were .31 and .32, respectively. We did not find evidence that the stability of OGM was moderated by the length of the test–retest interval. Furthermore, the stability coefficients for OGM for individuals with and without a lifetime history of major depressive disorder (MDD) were relatively similar in magnitude and not significantly different from one another (ρs=.34 and .42 for the proportions of specific and categoric memories for those with a history of MDD; ρs=.31 for both the proportions of specific and categoric memories for those without a history of MDD). Implications for the conceptualisation of OGM are discussed.     

Social Innovation: Enhancing Creative Performance Through Causal Analysis

ABSTRACT

Prior qualitative research has indicated that social innovation, the generation and implementation of new ideas about social relationships and social organization, requires active analysis of the causes operative in a social system. To provide some quantitative evidence bearing on this proposition, 180 undergraduates were presented with six social innovation problems drawn from the business and educational domains. Training in the analysis of causes was provided and manipulations were made to induce analysis through distancing and forecasting. It was found that induction of causal analysis through training and distancing contributed to the originality of obtained problem solutions especially in less familiar domains. The implications of these findings for understanding social innovation are discussed.     

Orienting Under Load: Intrinsic Dynamics and Postural Affordances for Visual Perception

Orientation toward one's surroundings is necessary for prospective control of action, and constraints on orienting activity have consequences for animal survival. Physically coupled load is a constraint for humans wearing protective equipment (firefighters, soldiers, etc.). The consequences of load on postural affordances while transitioning to upright stance was used to quantify the impact of different soldier configurations. Eight participants established upright posture in 4 relevant load configurations (5.0 to 79.2 lb). Load affected the accessibility of optical information at a distance as evidenced by increasing downward head angles and reductions in postural coordination. Reductions in the variability of time to establish upright stance with load suggests a loss of functional adaptability. Load asymmetries played a significant role as the most asymmetric configuration (not the heaviest) had the most detrimental effect on postural affordances. Center of Pressure (CoP) dynamics reflected the consequences of asymmetric loading on postural regulation as greater power and fluctuations across frequencies were observed. Physically coupled load induces significant constraints on orienting activity, and load asymmetry contributes significantly to the detrimental effects of protective equipment on action-perception coupling during whole-body movements.     

Investigating the Relationship Between Achievement Goals and Process Goals in Rugby Union Players

The present study investigated the relationship between achievement goal orientations and process goals in a sample of rugby union players. Participants were aged 14–45 years (M + SD: 24.31 + 6.02) and ranged from Club to National level. There were 78 males and 72 females with a mean of 9.17 years experience. Achievement goals were measured using an instrument developed by Harwood, Wilson, and Hardy (2002) Miller, M. B. 1995. Coefficient alpha: A basic introduction from the perspectives of classical test theory and structural equation modelling. Structural Equation Modelling, 2: 255–273. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] that assesses Self-Directed Task, Self-Directed Ego, Social Approval Task, and Social Approval Ego Goal Orientations. Process goals were measured using a slightly adapted version of an instrument developed by Harwood (1997) Harwood, C. G. 1997. Pre-competition achievement goals within young sports performers, Unpublished PhD Thesis UK: Loughborough University.  [Google Scholar]. Self-Directed Task (7), Self-Directed Ego (5), Social Approval Task (6), and Social Approval Ego (2) had varying numbers of significant positive correlations with process goal variables. Stepwise regression analysis revealed that Self-Directed Task was the sole significant predictor for six of the seven process goal variables (β = .30 to .60). Those significant others who influence the achievement context should encourage high levels of Self-Directed Task and discourage high levels of Social Approval Ego goal orientation to promote a focus upon the processes of performance.
