Cognitive processing and time perception

When a visual field is presented for 40 or 80 msec and a subject is asked to judge the duration of the stimulus, judged duration is found to be less when the field is blank than when the field contains three letters, but is the same whether the three letters form a word or not. The perceived difference between “filled” and “blank” fields increases when the subject is required to memorize the presented letters. These data are consistent with a theory which assumes,inter alia, that a stimulus is analyzed by a visual information processor and a timer, that attention is shared between these processors, and that temporal judgments are based on the output of both processors.     

The excess choice effect: The role of outcome valence and counterfactual thinking

Contrary to economic theory, psychological research has demonstrated increased choice can undermine satisfaction. When and why this ‘excess choice effect’ (ECE) occurs remains unclear. Building on theories of counterfactual thinking we argue the ECE is more likely to occur when people experience counterfactual thought or emotion and that a key trigger is a negative versus positive task outcome. Participants either selected a drink (Experiment 1) or chocolate (Experiment 2) from a limited (6) versus extensive (24) selection (Experiment 1) or were given no choice versus extensive (24) choice (Experiment 2). In both experiments, however, the choice was illusory: Half the participants tasted a ‘good’ flavour, half a ‘bad’ flavour. As predicted, extensive choice was only detrimental to satisfaction when participants tasted the ‘bad’ drink or chocolate, and this was mediated by the experience of counterfactual thought (Experiment 1) or emotion (Experiment 2). When outcomes were positive, participants were similarly satisfied with limited versus extensive and no choice versus extensive choice. Implications for our theoretical understanding of the ECE and for the construction of choice architectures aimed at promoting individual satisfaction and well‐being are discussed.     

Teaching Mathematics for Spatial Justice: An Investigation of the Lottery

This article explores integrating place-based education with critical mathematics toward teaching mathematics for spatial justice. Local Lotto, a curricular module with associated digital tools, was designed to investigate the lottery as a critical spatial phenomenon and piloted in urban high schools. This article describes findings from the second iteration in a remedial class in a low-income neighborhood. The research questions consider how the spatial focus supported the learning of mathematics and provided opportunities for students to think critically about the lottery using that mathematics. Findings include student interest in and engagement with the theme of the lottery familiar from outside of school with associated social justice implications. Students used mathematics and spatial evidence, at various levels of spatial scale, to support arguments about the lottery with greater success at narrower levels of scale. Suggestions about further innovations to scaffold place in a “critical pedagogy of place” in mathematics are provided.     

The Sounds of Silence: Inferences from the Absence of Word‐of‐Mouth

While past work has explored some of the reasons why people themselves may remain silent in a group, almost no research has examined the mirror image of this question: How do consumers construe the silence of others? Do they project the opinions of the speakers in a conversation onto the silent individuals, assuming that silence signals agreement? Do they have a usual or “default” naïve theory of silence that they use to explain it across multiple contexts—i.e., “silence usually signals disagreement?” Or does silence act as a mirror, reflecting observers’ own opinions back at them? Three experiments contrasted perceivers’ estimates of conversational silence with their estimates of unknown opinions outside the conversation. Estimates of opinions outside the conversation generally followed an agreement‐with‐the‐speakers rule—the more an opinion was expressed in the group, the more consumers assumed others would support it too. In contrast, silence inside the conversation was interpreted very differently, serving as a mirror for participants’ own thoughts, even when the vocal majority favored the opposite position. Results suggest a process whereby observers project the reason they personally would have been silent in the group (given their opinion) onto silence, leading to an inference that the silents agree with the self.     

Changing Definitions of Work and Play: Importance of Workplace Humour

World famous actor-comedian Charlie Chaplin once said that “A day without laughter is a day wasted”. But try applying the same quote in our work place, with fluctuating markets, unending competition and impossible deadlines; we may find more wasted days than the rest. All of us know what it feels to experience humour, but most of us think twice before having a hearty laugh at our workplace. What is the barrier which stops us from sharing humour at work? This paper attempts to answer this question and aims to understand the concept of humour at workplace and its importance in today’s context. It aims to review existing literature in this field and present the application of Workplace humour in an organizational context to achieve favourable work-related outcomes. In addition to this, the paper also enumerates the different workplace practices that are directly or indirectly related to humour and provide suggestions to organizations on how to use this powerful tool to bring about organizational effectiveness.     

König's Infinity Lemma and Beth's Tree Theorem

König, D. [1926. ‘Sur les correspondances multivoques des ensembles’, Fundamenta Mathematica, 8, 114–34] includes a result subsequently called König's Infinity Lemma. Konig, D. [1927. ‘Über eine Schlussweise aus dem Endlichen ins Unendliche’, Acta Litterarum ac Scientiarum, Szeged, 3, 121–30] includes a graph theoretic formulation: an infinite, locally finite and connected (undirected) graph includes an infinite path. Contemporary applications of the infinity lemma in logic frequently refer to a consequence of the infinity lemma: an infinite, locally finite (undirected) tree with a root has a infinite branch. This tree lemma can be traced to [Beth, E. W. 1955. ‘Semantic entailment and formal derivability’, Mededelingen der Kon. Ned. Akad. v. Wet., new series 18, 13, 309–42]. It is argued that Beth independently discovered the tree lemma in the early 1950s and that it was later recognized among logicians that Beth's result was a consequence of the infinity lemma. The equivalence of these lemmas is an easy consequence of a well known result in graph theory: every connected, locally finite graph has among its partial subgraphs a spanning tree.     

A Comparative Analysis of the Psychological Literature on Collaboration Between Clergy and Mental-Health Professionals—Perspectives from Secular and Religious Journals: 1970–1999

A search of the psychological literature was conducted to obtain a better understanding of the issues surrounding collaboration between clergy and psychologists. An electronic search of PsycINFO for 1970–1999 ultimately yielded 52 articles in secular journals and 37 articles in religiously oriented journals that discussed collaboration. Whereas interest in collaboration peaked in religious journals during the 1980's, the number of articles on collaboration appearing in secular journals increased significantly from 1970 to 1999. Content analysis confirmed six major themes about collaboration found by A. J. Weaver, K. J. Flannelly, L. T. Flannelly, and J. E. Oppenheimer (2003). One of the most common themes was the clergy's role as frontline mental-health workers, which was mentioned significantly more often in secular than religious journals. The need for greater education and knowledge was also mentioned significantly more often in secular than religious journals. Insufficient knowledge or education was frequently seen as an obstacle to collaboration. Other factors affecting collaboration are discussed.     

The effect of message framing on self-management of chronic pain: a new perspective on intervention?

This study examines framed messages as a novel approach to promote self-management of chronic pain. Primary care patients reporting chronic pain (pain rated ≥?4 on 0-10 NRS-I for ≥3 months) were randomly assigned to receive a gain- or loss-framed message promoting self-management of pain. Impact of the framed message on behavioural self-management (including communicating with providers, relaxation, activity pacing, pleasant activities and healthy lifestyle) was assessed. Post-message, individuals in the loss-frame condition reported significantly greater interest in and more knowledge gained from the information presented in the message (p≤0.03). Loss-frame participants were significantly more likely to express confidence that they would practice relaxation (p≤0.03). Pain readiness to change, pain self-efficacy and message frame independently influenced motivation to engage in relaxation as a self-management strategy. Across all behaviours assessed, there were no observed interactions between message frame and either pain self-efficacy or pain readiness to change (p>0.05). Framing may be useful to promote pain self-management; larger trials are needed to fully evaluate its potential and to further assess the applicability of framed communication to impact a broader range of chronic conditions.     

Experiences related to expert supervisors' views of ideal therapeutic practice

Aims: This study examines the relationship between expert supervisors' professional experiences and their views about the importance of different psychotherapy techniques. Method: Thirty psychodynamic‐interpersonal (PI) supervisors and 13 cognitive‐behavioural (CB) supervisors (N=43) were instructed to rate 20 therapeutic techniques according to how characteristic each technique is of an ideally‐conducted session within their theoretical orientation. The measure used for this assessment was the Comparative Psychotherapy Process Scale. Results: Findings demonstrated that supervisors' beliefs about ideal therapeutic techniques are related to their number of years in post‐graduate clinical practice, training, and supervising trainees, as well as to the number of publications they have authored. Further, experience within a given orientation tends to lead to a greater endorsement of techniques within that orientation, although this finding is more uniform for CB supervisors than PI supervisors. Finally, differential types of experience lead to differential focusing on specific techniques. Discussion: The clinical importance of these findings is explored.
