This paper reports a study of planning processes in the five-disc Tower of London (TOL) task in 20 younger and 20 older adult participants. A concurrent direct ''think-aloud'' method was used to obtain data on planning processes prior to moving discs in the TOL. A check was made of the effects of verbalising by comparing performance data from the experimental groups with data from control groups who did not verbalise during planning or moving. Verbalising slowed down planning and moving but (...) did not appear to distort the participants' approaches to the task. Older and younger participants did not differ in average moves taken to solve the tasks. However, older participants' planning was less complete and more error-prone than that of younger participants. The planning processes were characterised as showing a means-ends ''goal selection'' strategy. In this strategy participants (1) identify a single active goal disc at the start, (2) select moves and move sequences to enable the placing of the current goal disc in its target position, and (3) continue in this way until all discs are in their target positions. Age differences were found in the planning stage, during which there was no stimulus support and hence a substantial working memory load. During the move phase there was stimulus support and hence little loading of working memory. Age differences in moves required were not found in the move phase. As older participants tend to have depleted working memory capacity the present results suggest that working memory is heavily loaded in TOL planning but less so in the move phase of TOL. (shrink)

This paper reports a study of the roles of visuo-spatial and verbal working memory capacities in solving a planning task - the five-disc Tower of London (TOL) task. An individual differences approach was taken. Sixty adult participants were tested on 20 TOL tasks of varying difficulty. Total moves over the 20 TOL tasks was taken as a measure of performance. Participants were also assessed on measures of fluid intelligence (Raven's matrices), verbal short-term storage (Digit span), verbal working memory span (Silly (...) Sentence span), visuo-spatial short-term storage (Visual Pattern span and Corsi Block span), visuo-spatial working memory (Corsi Distance Estimation), visuo-spatial processing speed (Manikin test), and verbal speed (Rehearsal speed). Exploratory factor analysis using an oblique rotation method revealed three factors which were interpreted as (1) a visuo-spatial working memory factor, (2) an age-speed factor, and (3) a verbal working memory factor. The visuo-spatial and verbal factors were only moderately correlated. Performance on the TOL task loaded on the visuo-spatial factor but did not load on the other factors. It is concluded that the predominant goal-selection strategy adopted in solving the TOL relies on visuo-spatial working memory capacity and particularly involves the active ''inner scribe'' spatial rehearsal mechanism. These correlational analyses confirm and extend results previously obtained by use of dual task methods, (Phillips, Wynn, Gilhooly, Della Sala, & Logie, 1999). (shrink)

Memory and forgetting are inextricably intertwined. In order to understand how memory works we need to understand how and why we forget. The topic of forgetting is therefore hugely important, despite the fact that it has often been neglected in comparison with other features of memory. This volume addresses various aspects of forgetting, drawing from several disciplines, including experimental and cognitive psychology, cognitive and clinical neuropsychology, behavioural neuroscience, neuroimaging, clinical neurology, and computational modeling. The first chapters of the book discuss (...) the history of forgetting, its theories and accounts, the difference between short-term and long-term forgetting as well as the relevance of forgetting within each of the numerous components of memory taxonomy. The central part summarizes and discusses what we have learned about forgetting from animal work, from computational modeling, and from neuroimaging. Further chapters discuss pathological forgetting in patients with amnesia and epilepsy, as well as psychogenic forgetting. The book concludes by focusing on the difference between forgetting of autobiographical memories versus collective memory forgetting. This book is the first to address the issue of forgetting from an interdisciplinary point of view, but with a particular emphasis on psychology. The book is scientific and yet accessible in tone, and as such is suitable for advanced undergraduate and postgraduate students of psychology and related subjects, such as science and neuroscience.

Tall tales presents a sweeping survey of common myths about the mind and brain. In a lighthearted and accessible style, it exposes the truth behind these beliefs, how they are perpetuated, why people believe them, and why they might even exist in the first place.

Working-memory retention as activated long-term memory fails to capture orchestrated processing and storage, the hallmark of the concept of working memory. The event-related potential (ERP) data are compatible with working memory as a mental workspace that holds and manipulates information on line, which is distinct from long-term memory, and deals with the products of activated traces from stored knowledge.

In this paper we focus our attention on tableau methods for propositional interval temporal logics. These logics provide a natural framework for representing and reasoning about temporal properties in several areas of computer science. However, while various tableau methods have been developed for linear and branching time point-based temporal logics, not much work has been done on tableau methods for interval-based ones. We develop a general tableau method for Venema's \cdt\ logic interpreted over partial orders (\nsbcdt\ for short). It combines (...) features of the classical tableau method for first-order logic with those of explicit tableau methods for modal logics with constraint label management, and it can be easily tailored to most propositional interval temporal logics proposed in the literature. We prove its soundness and completeness, and we show how it has been implemented. (shrink)

ObjectiveAlthough childhood adversity can have lasting effects into later life, positive adaptations have also been observed, including an increased tendency toward prosocial behavior. However, little is known about the link between childhood adversity and later life prosocial behavior, with a particular scarcity of research on intrafamilial childhood adversity. Therefore, this study aimed to examine older adult's experiences of childhood adversity and identify mechanisms linked to prosocial behavior. Two adversity contexts were compared to explore individual, as well as broader cultural and (...) contextual mechanisms linking childhood adversity and later life prosocial behavior.MethodSemi-structured interviews were conducted with N = 29 Irish adult survivors of childhood adversity: n = 12 intrafamilial survivors, n = 17 institutional survivors. Interviews were analyzed using the framework analysis method, with reference to the conceptual model of altruism born of suffering.ResultsFive themes were identified on prosocial mechanisms, with three themes in both survivor groups, and two group-specific themes.ConclusionResults identified motivational processes and volitional factors linked to later life prosocial behavior. Connections to caring roles, support, and social norms in childhood, as well as the need for a sense of purpose and meaning from the adversities in adulthood, highlight potential targets for psychotherapeutic intervention to promote prosocial responding and positive adaptation for childhood adversity survivors.

In lieu of an abstract, here is a brief excerpt of the content:Ralegh and the Punic WarsCharles G. Salas“For he doth not feign, that rehearseth probabilities as bare conjectures....”Sir Walter Ralegh, The History of the WorldThe Secret HistoryIn 1603 Sir Walter Ralegh was judged guilty of treason and imprisoned in the Tower of London to await execution. The wait was a long one —execution did not take place until 1618—giving this artful courtier, warrior, poet, and poseur time to script new (...) roles for himself. The most memorable of these was historian, and the stage on which he performed was the entire world. Universal history had been a time-honored genre in England, but never had there been so remarkable a performance by a native son as Ralegh’s The History of the World (1614). In five books Ralegh offered to king and country his interpretation of events from Creation to 168 bc. Book V, last and lengthiest of the entire work, deals in large part with the struggle between Rome and Carthage. The story of that struggle is Ralegh’s most mature historical writing and the most revealing of himself, for when he gave up his plan to carry his history into modern times, the Punic Wars became the context for things about the present that he was loath to leave unsaid.Despite its length (about a million words) and premature ending, the History was an enormous success with a public eager to possess the meaning of it all. Oliver Cromwell particularly liked the way it followed “the strange windings and turnings of Providence”; 1 no doubt he found Ralegh’s emphasis upon the Providential control of events reassuring. For Ralegh claimed to show how “kings and kingdoms have flourished and fallen, and for what virtue and piety God made prosperous, and for what vice and deformity he made wretched both the one and the other.” 2 In fact what Ralegh showcased [End Page 195] were the acts of a vengeful, Old Testament God more concerned with punishing monarchical sins than with making monarchs prosperous, and the History was temporarily suppressed by James for being “too saucy in censoring princes.” 3If the king did not like what he saw in the History, the king’s critics did; and Ralegh, never a friend to Puritan or republican in his lifetime, became a hero to both as a pious author and victim of Stuart tyranny. Those sympathetic to the Stuarts, like Alexander Ross, Chaplain to Charles I, saw Ralegh rather differently; but the popularity of the man and his History could not be denied. Ross himself profited from that popularity by doing both an abridgment and a continuation of the History as well as Som Animadversions and Observations upon Sir Walter Raleigh’s Historie of the World. Wherein his mistakes are noted, and som doubtful passages cleered (1653). Many of these animadversions were directed at Ralegh’s treatment of the Punic Wars. Ross recognized that “mistakes” and “doubtful passages” there formed a pattern: “Sir Walter cannot look upon the Roman Glorie with but a squint eye”(8), he complained. But did he also recognize the reason for that squint eye, that Ralegh kept one eye on the past and the other on the present? That many of those “doubtful passages” were in fact strategic elements in a campaign (based on parallels) against Rome, against James, and against James’s ministry? Had this been obvious to Ross, he still would not have said so. Writing under Cromwell, he could no more afford to complain explicitly about abuse of James than Ralegh, writing under James, could afford to make the abuse explicit.Parallels—implicit or imagined—are part and parcel of Ralegh’s providentialism. In brief: God controls events, God does not change, events do not change. This is not to say that Ralegh believed that God’s control was transparent, that God couldn’t change, or that free will did not exist. Ralegh did not solve the great problems of theology. 4 What he is sure about is that the same sins continue to be punished just as they have always been: “So also hath God punished the same and the like sins in all after-times, and...

In questo articolo si analizzano congiuntamente l'origine delle idee e il loro uso regolativo. A questo scopo si comincia considerando la connessione tra uso logico della ragione e definizione della ragione in generale come facoltà dei principi. Si considera poi come la rappresentazione di un incondizionato derivi necessariamente dall'uso logico, e come quindi questo implichi necessariamente un uso reale della ragione. Si considera poi come le varie rappresentazioni dell'incondizionato diano origine alle idee trascendentali. Infine, si considera l'uso (...) regolativo delle idee alla luce della pratica di inferire dal quale derivano. (shrink)
