resultaten van deze studie

A

In Experiment 1 we found that cueing future thinking had no effect on 8–11-year-olds’ (n = 177) delay discounting of either real or hypothetical rewards. In Experiment 2 we found that cueing adolescents (12–14-year-olds, n = 126) and adults (n = 122) to think about personal future events decreased their discounting of delayed rewards relative to three other conditions: a no cue control, an episodic memory condition and a novel ‘future other’ condition in which individuals imagine future events that might happen to a significant other person in their life. Cueing adults and adolescents to think about personal future events did not however affect how connected they felt to their future selves or their subjective sense of how close future time points felt to them – two constructs that have previously been shown to be related to delay discounting.

Q

wat was het doel van experiment 2

A

Second, we introduced a novel control condition (Experiment 2) to the study of adult and adolescent delay discounting – a ‘future other’ condition in which participants were cued to think about specific future events that would happen to a significant other person they know. Employing this control condition enabled us to examine whether cueing effects hinge specifically upon engaging in EFT (which by definition concerns one’s personal future), or instead result from more general future-oriented cognition.

Q

wat was het derde doel van deze studie

A

And, third, we examined two possible mechanisms that might connect EFT cueing to decreased discounting:
(1) increased future self-connectedness and
(2) changes to one’s subjective sense of future time

Q

wat wordt bedoeld met future time perception

A

the subjective perception of the temporal distance between the present and future time
points. When people make judgments about how far away different future time points feel subjectively, the relativ difference between them may not match the actual objective ratio. Rather, events farther away in time may seem closer together to one another than events in the near future. That is, there may be increasing compression of subjective time as objective time increases.

Q

experiment 1 methode

A

Children completed two tasks assessing
intertemporal decision making: a delay choice task involving real rewards and a delay discounting task involving hypothetical monetary rewards, under one of three conditions.

  • EFT condition: children were cued to think about events from personal future
  • episodic memory condition: children were cued to think about past
  • control condition: children were not cued

future time perception was measured by letting them pull a string from a box to indicate how far away four time points were to them.

first they did a delay choice task: were offered a choice between a low value reward (1 van het item) available immediately, and a high value reward (2 van het item) available after a delay. they had to choose.
- with EFT: imagine visiting grandma next week (daarna de vraag of ze 20 pound volgende week willen, of 10 pound nu).

then they were tested on the delay discounting task, with hypothetical monetary rewards.

Q

Our main finding was that cueing children to think about events either from their personal future or past prior to making intertemporal decisions had no effect on their propensity to discount delayed rewards.

This was true for both a delay choice task involving real rewards and a delay discounting task with hypothetical monetary rewards.

Q

hoe meetten ze bij exp 2 de future self-connectedness en future time perception

A
  • future self-connectedness: compare the person they are in the present, to the person they will be 1 year in the future. then asked to judge how much they overlap.
  • future time perception: . On each trial, participants were presented with two interlocking cogs placed inside a small square. The experimenter explained that the participant’s task was to think about how far away different times in the future feel to them. To do so they would position the cursor in the square on the screen and press and hold to indicate how far each time point felt

Q

They indicate that EFT cueing is ineffective before adolescence, at least as typically employed in the context of delay discounting studies. It remains to be seen whether modifications of cueing techniques may be possible that are effective when used with children. By adolescence, such effects are robust, and we found that they were observable only when theoretically significant cues were used that specifically involved EFT. However, we found no evidence for two plausible hypotheses about the mechanism underpinning EFT cueing – that such cueing affects the degree to which participants feel connected to their future selves, or that it affects the subjective distance of future points in time

Adolescents tended to discount future rewards across all conditions
to a greater extent than adults, replicating the developmental pattern
commonly reported elsewhere

Q

The second way our findings extend previous research stems from our use of a novel control condition, the Future Thinking-Other condition, in which participants described a specific future event that they anticipated may be experienced by a close associate. Despite this task differing only from the EFT condition in terms of whether the event was to be personally experienced or not, the cueing effect on delay discounting was observed only in the EFT condition
