Five experiments investigated the influence of picture processing on recollective experience in recognition memory. Subjects studied items that differed in visual or imaginal detail, such as pictures ...versus words and high-imageability versus low-imageability words, and performed orienting tasks that directed processing either toward a stimulus as a word or toward a stimulus as a picture or image. Standard effects of imageability (e.g., the picture superiority effect and memory advantages following imagery) were obtained only in recognition judgments that featured recollective experience and were eliminated or reversed when recognition was not accompanied by recollective experience. It is proposed that conscious recollective experience in recognition memory is cued by attributes of retrieved memories such as sensory-perceptual attributes and records of cognitive operations performed at encoding.
The relationship between creativity and susceptibility to associative memory illusions in the Deese/Roediger–McDermott procedure was investigated using a multiple regression analysis. Susceptibility ...to false recognition was significantly predicted by performance on a measure of convergent thinking (the Remote Associates Task) but not by performance on a measure of divergent thinking (the Alternative Uses Task). These findings suggest that the ability to engage in convergent (but not divergent) thinking underlies some of the individual variation in susceptibility to associative memory illusions by influencing the automaticity with which critical lures are activated at encoding.
A growing interest has emerged in the role that autobiographical memory retrieval plays in simulation of future events. Cognitive explorations in this domain have generally relied on cue word ...paradigms with instructions to develop specific (relating to one particular day) memories or future events. However, the usefulness of this paradigm has been questioned with respect to its ability to assess habitual patterns of retrieval within autobiographical memory. The current study investigated similarities and differences in how participants spontaneously remember the past and imagine the future when the specificity constraints inherent in the cue word task are removed. A total of 93 undergraduate students completed two sentence-completion tasks, probing for past and future events. A number of differences emerged between past and future thought; in particular, they were less specific when simulating future events compared with past events. This reduction in specificity was the result of participants producing more future thoughts relating to extended lifetime periods and semantic associates. The findings are discussed in relation to the underlying cognitive processes involved in autobiographical memory retrieval and future event simulation.

•Investigated the elaboration of past and future autobiographical events.•Elaboration times were faster when reported in forwards chronological order.•No difference in elaboration times for past vs. ...future events.•Elaboration of future (but not past) events was faster when related to current goals.
Five experiments investigated the cognitive processes involved in the elaboration of past and future events. A production listing procedure was used, in which participants listed details of each event in forwards chronological order, backwards chronological order, or free order. For both past and future events, forwards and free ordering conditions were reliably faster than backwards order. Production rates between past and future temporal directions did not differ in Experiments 1a, 1b, and 3. However, in Experiment 2, the elaboration of future events was faster than the elaboration of past events. This pattern can be explained by the findings of Experiment 4, in which production rates were faster for likely events than for unlikely events but only in the future condition. Overall, the findings suggest that the elaboration of future, but not past, events, is facilitated when constructed around current goals.
The police often appeal for eyewitnesses to events that were unlikely to have been emotive when observed. An eyewitness, however, may be in a negative mood whilst encoding or retrieving such events ...as mood can be influenced by a range of personal, social, and environmental factors. For example, bad weather can induce a negative mood. This experiment compared the impact of negative and neutral moods during encoding and/or retrieval upon eyewitness recall of a non-emotive event. A negative mood during encoding had no impact upon the number of correct details recalled (provided participants were in a neutral mood at retrieval) but a negative mood during retrieval impaired the number of correct details recalled (provided participants were in a neutral mood at encoding). A negative mood at both time points enhanced the number of correct details recalled, demonstrating a mood-dependent memory enhancement. The forensic implications of these findings are discussed.

► Mental toughness is positively associated with directed forgetting. ► Cognitive inhibition underpins mental toughness. ► Findings suggest an adaptive role for cognitive inhibition.
The concept of ...mental toughness has been found to be related to outcome performance measures in sport and other competitive situations. Despite this, little attention has been devoted to understanding the cognitive mechanisms that underlie mental toughness. The current study attempted to identify the cognitive underpinnings of mental toughness using the directed forgetting paradigm, in which participants are given a surprise memory test for material they were previously instructed to forget. Regression analyses showed that mental toughness, as measured by the MTQ48 (Clough, Earle, & Sewell, 2002), did not influence the recall of a to-be-forgotten list, but participants with high mental toughness showed better recall of a to-be-remembered list following instructions to forget the previous list. The superior recall of the to-be-remembered list suggests that mentally tough individuals have an enhanced ability to prevent unwanted information from interfering with current goals. These findings support the proposal that cognitive inhibition is one of the mechanisms underpinning mental toughness.
A postal survey was sent to members of the Association of Cardiothoracic Anaesthetists to ascertain current practice in the use of pharmacological agents as cerebral protectants during deep ...hypothermic circulatory arrest. The response rate was 60%. Eighty-three per cent of respondents used some form of pharmacological agent specifically for cerebral protection. Fifty-nine per cent of respondents used thiopental, 29% used propofol and 48% used a variety of other agents, the most common of these being a steroid. There were variations in the dose and timing of administration of drugs. Few respondents believed that there was a body of evidence to support this use of pharmacological agents. Only 35% of respondents believed there to be sufficient evidence to support the use of thiopental. Similarly, only 11% of respondents believe that there is evidence supporting the use of propofol, and 16% the use of steroids. The above findings demonstrate that it would not be possible to create a "best practice" set of guidelines at present. A national database of all cases of adult thoracic surgery involving deep hypothermic cardiac arrest, with methodology and outcome, could probably establish such guidelines, evidence based.

The Klein effect (
G. S. Klein, 1964
) refers to the finding that high-frequency words produce greater interference in a color-naming task than low-frequency words. The present study used the Klein ...effect to investigate the relationship between frequency and age of acquisition (AoA) by measuring their influence on color naming. Two experiments showed reliable effects of frequency (though in the opposite direction to that reported by Klein) but no effects of AoA. Experiment 1 produced a dissociation between frequency and AoA when manipulated orthogonally. Experiment 2 produced the same dissociation using different stimuli. In contrast, both variables reliably influenced word naming. These findings are inconsistent with the view that frequency and AoA are 2 aspects of a single underlying mechanism.
Two experiments investigated the effects of reinstating encoding operations on remember and know responses in recognition memory. Experiment 1 showed that reinstating an effortful encoding task ...(generating words from fragments) increased remember responses at test but reinstating an automatic encoding task (reading intact words) did not. This pattern was confirmed in Experiment 2 in which words were either read intact or generated from anagrams. These findings show that repeating effortful (but not automatic) encoding operations at test cues not only the recognition of the information that was acquired via those operations but also the conscious recollection of the encoding episode.
Previous research has highlighted the wide individual variability in susceptibility to the false memories produced by the Deese/Roediger–McDermott (DRM) procedure. This study investigated whether ...susceptibility to false memories is influenced by individual differences in the specificity of autobiographical memory retrieval. Memory specificity was measured using the Sentence Completion for Events from the Past Test (SCEPT). Memory specificity did not correlate with correct recognition, but a specific retrieval style was positively correlated with levels of false recognition. It is proposed that the contextual details that frequently accompany false memories of non-studied lures are more accessible in individuals with specific retrieval styles.
