Does episodic future thinking improve prospective remembering

Extant findings suggest interesting avenues for the investigation of the potential relationship between EFT and PM. However, as they stand, they are inconclusive as to the causal role that EFT may play in aiding prospective remembering. In one Experiment, we showed that accuracy in a prospective memory (PM) task performed on the second day was significantly higher when participants, on the first day, had mentally simulated the sequence of events expected to occur on the second day, including the PM task, than when they had performed control tasks. These data extend previous findings on the functional benefit of future simulations in different domains by revealing a substantial facilitation effect of future-oriented thoughts on PM performance when the mentally simulated future task matched the actually executed task.

Desirable and undesirable future thoughts call for different scene construction processes

Despite the growing interest in the ability of foreseeing (episodic future thinking), it is still unclear how healthy people construct possible future scenarios. We suggest that different future thoughts require different processes of scene construction. Thirty-five participants were asked to imagine desirable and less desirable future events. Imagining desirable events increased the ease of scene construction, the frequency of life scripts, the number of internal details, and the clarity of sensorial and spatial temporal information. The initial description of general personal knowledge lasted longer in undesirable than in desirable anticipations. Finally, participants were more prone to explicitly indicate autobiographical memory as the main source of their simulations of undesirable episodes, whereas they equally related the simulations of desirable events to autobiographical events or semantic knowledge. These findings show that desirable and undesirable scenarios call for different mechanisms of scene construction. The present study emphasizes that future thinking cannot be considered as a monolithic entity.

Computer-Based "Mental Set" Tasks: An Alternative Approach to Studying Design Fixation

The term “design fixation” refers to a phenomenon where designers unknowingly limit the space within which they search for solutions. In an attempt to study this phenomenon experimentally, researchers typically set participants open-ended design problems, prime them with an example solution, and measure their performance through a variety of subjective metrics. This approach gives rise to various problems, including limited data capture and highly subjective evaluation of design behavior. To address these problems, we studied design fixation with a computer-based task inspired by psychological paradigms used to study “mental set” (also known as the “Einstellung effect”). The task consisted of a gamelike activity requiring participants to design a bridge within a specified budget. The use of a digital environment facilitated continuous data capture during the design activities. The constrained task (and direct quantitative measures) permitted a more objective analysis of design performance, including the occurrence of fixation. The results showed that participants who developed a mental set during the task failed to find alternative, more efficient solutions in trials admitting multiple solutions, compared to the participants who did not fall victim to this mental block. In addition, during the process of designing, the occurrence of mental set resulted in participants adopting a less efficient design behavior and reporting a different subjective experience of the task. The method used and the results obtained show an exciting alternative for studying design fixation experimentally and promote a wider exploration of the variety of design activities in which fixation might occur.

Effects of self-generated versus experimenter-provided cues on the representation of future events.

Most experimental studies of prospection focused on episodic forms of future events prompted by means of verbal cues. However, there is evidence suggesting that future events differ considerably according to whether they are produced in response to external, experimenter-provided verbal cues or they are self-generated. In the present study, we compared the quality, the phenomenal characteristics, the temporal distribution, and the content of imagined events prompted by experimenter-provided cues (i.e., cue-words and short verbal sentences) or elicited by means of verbal cues that were self-generated in an autobiographical fluency task. The results showed that future events prompted by means of self-generated cues contained fewer event-specific details than future events prompted by experimenter-provided cues. However, future events elicited by means of self-generated and by experimenter-provided cues did not differ with respect to their phenomenal characteristics. The temporal distribution and the thematic content of future representations were also affected by the type of cue used to elicit prospection. These results offer a holistic view of the properties of future thinking and suggest that the content and the characteristics of envisioned future events may be affected by the method used to elicit prospection.

Visual complexity accentuates picture description deficit in amnesia

Objective: A recent study indicated that amnesic patients have difficulties not only in describing past and imagined scenarios, but also in describing pictures that are in full view. This finding suggests that impaired memory hampers descriptions of scenarios more broadly. However, no such impairment in picture description in amnesic patients was observed in a related study. One key methodological difference between these studies was the complexity of the pictures to be described, hinting that group differences might be marked only if pictures are sufficiently complex to tax aspects of memory. Method: To test this complexity hypothesis, we examined whether differences in picture description between amnesic patients and controls increase with increasing picture complexity. As in previous studies, we also assessed our participants’ ability to describe imagined scenarios. Results: Amnesic patients reported significantly fewer elements than did controls when describing pictures and imagined scenarios. The group difference in picture description was significantly larger for complex than for simple pictures. Conclusion: Although variations in lesion sites might have accounted for the aforementioned cross-study differences in picture description in amnesic patients, our results suggest that, at least in amnesic patients with extramedial temporal lobe lesions, the complexity of pictures can determine whether or not a (substantial) picture-description deficit is observed. We interpret these findings in terms of a narrative-construction deficit. We hypothesize that, whereas brief narrative can be constructed via nonmemory cognitive processes, the construction of more detailed narrative depends upon intact functioning of a temporary memory system, such as the episodic buffer.

Idea representation and elaboration in design inspiration and fixation experiments

Abstract Design fixation experiments often report that participants exposed to an example solution generate fewer ideas than those who were not. This reduced ‘idea fluency’ is generally explained as participants’ creativity being constrained by the example they have seen. However, the inclusion of an example also introduces other factors that might affect idea fluency in the experiments. We here offer an additional explanation for these results: participants not exposed to the example tend to generate ideas with little elaboration, while the level of detail in the example encourages a similar level of elaboration among stimulated participants. Because idea elaboration is time consuming, non-stimulated participants record more ideas overall. We investigated this hypothesis by reanalyzing data from three different studies; in two of them we found that non-stimulated participants generated more ideas and more ideas containing only text, whilst stimulated participants generated ideas that were more elaborated. Based on the creativity literature, we provide several explanations for the differences in results found across studies. Our findings and explanations have implications for the interpretation of creativity experiments reported to date and for the design of future studies.
