Effects of Context and Framing on Choosing Food Products: Combining Behavioral and Psychophysiological Data to Predict Consumer Decisions
2015.04~2016.03, 代表者:ローレンス ヨハン, Kyushu University
Human decision-making is often influenced by the way in which choice options are presented. Though context and framing effects have long been studied in a variety of decision-making situations, the underlying principles have remained difficult to elucidate. This difficulty is naturally due to the inherent complexity of real-life situations, where various factors combine to produce variable patterns of results. The same context may affect the same person in a different way depending on accidental elements, such as whether a certain piece of information appears in the person’s field of view. Here we argue that, to make the decisions more tractable, it is essential to focus on the dynamics of the choice processes. Our working hypothesis is that the combination of behavioral tracking and psychophysiological measurement produces reliable estimates of the decision-maker’s internal state, particularly with respect to the level of attention and the emotional response toward different items. For instance, an increased amount of attention, combined with a positive affect, would predict a choice in favor of the product under consideration, whereas an increased amount of attention, combined with a negative affect, would predict a rejection. In this project we focus on food choices, and examine the effects of context and framing (e.g., varying the cultural cues, or the amount of additional information about price, caloric content, etc.). We hypothesize that the susceptibility to context and framing effects may show a dynamical pattern, depending on the subjects’ cognitive and cultural characteristics but also depending on their internal or motivational state (e.g., shortly after a meal). In our project, we aim to find out which people are susceptible to which kinds of context and framing effects. With such knowledge, it may be possible in future to design strategic campaigns to promote people’s health by protecting them against harmful contextual influences..
ラット海馬における「自己」と「他者」の空間表現のメカニズム
2012.04~2014.03, 代表者:ローレンス ヨハン, 九州大学, 日本
ラット海馬における場所ニューロンは、ラット自身(自己)の実験環境内における空間認知(位置の認識)に用いられていると考えられており、認知地図仮説の神経科学的根拠となっている。しかしその認知地図が実世界の事象を完全に表現するためには、これらの場所ニューロンが同じ環境内を移動する「他者」の行動を観察した際にも同様の活動特性を示してしかるべきである。本研究は、他者の行動に対するラット海馬の場所ニューロンの活動特性を明らかにし、海馬領域の空間認知に関するミラーシステムとしての可能性を検討することを目的とする。.
Deliberative decision making in rats
2010.09~2013.08, 代表者:Redish, A. D., University of Minnesota, United States of America, Scotland, & Japan
Deliberation entails the transient consideration of potential consequences of actions so as to determine the best choice. Rats, monkeys, and humans have all been found to deliberate over difficult decisions, particularly when faced with uncertain or newly-learned contingencies. Recently, we and other labs have found direct evidence for representations of potential future events in rats that behaviorally appear to be deliberating over decisions. However, the mechanisms by which deliberation aids in decision-making, the mechanisms by which choices are selected to be considered, and the relationship between deliberation and other categorizations of decision-making are all still unknown. From a psychological perspective, non-deliberative decisions can be described as ones that are made rapidly, and don't require elaborative cognitive processing. Deliberative decisions, in contrast, are slower, require more cognitive processing, and involve more uncertainty. From a neuroscience perspective, we can tackle this distinction explicitly: do deliberative and non-deliberative decisions depend on different brain circuits? If so, then these two types of decisions represent distinct classes of neural and cognitive events. If not, decision-making may be a single process that differs in the amount of processing involved within the same neural circuit.

Deliberative decision making is an internally-generated process based on covert variables and thus its mechanisms cannot be studied through standard behavioral neuroscience techniques. This means that a scientific study of deliberative decision making will require a combination of techniques drawn from different disciplines. Our project is the first venture of this kind, combining large ensemble neural recording (Redish), lesion and inactivation (Wood and Dudchenko), complex behavioral analysis and small ensemble neural recording (Lauwereyns), and the mathematics of dynamical systems (Tsuda)..

Noha Zommara, Muneyoshi Takahashi, Johan Lauwereyns, Influence of multiple action-outcome associations on the transition dynamics toward an optimal choice in rats. , Cognitive Neurodynamics, https://doi.org/10.1007/s11571-017-9458-9, 2018.01, When faced with familiar versus novel options, animals may exploit the acquired action–outcome associ- ations or attempt to form new associations. Little is known about which factors determine the strategy of choice behavior in partially comprehended environments. Here we examine the influence of multiple action–outcome associ- ations on choice behavior in the context of rewarding outcomes (food) and aversive outcomes (electric foot- shock). We used a nose-poke paradigm with rats, incor- porating a dilemma between a familiar option and a novel, higher-value option. In Experiment 1, two groups of rats were trained with different outcome schedules: either a single action–outcome association (‘‘Reward-Only’’) or dual action–outcome associations (‘‘Reward-Shock’’; with the added opportunity to avoid an electric foot-shock). In Experiment 2, we employed the same paradigm with two groups of rats performing the task under dual action–out- come associations, with different levels of threat (a low- or high-amplitude electric foot-shock). The choice behavior was clearly influenced by the action–outcome associations, with more efficient transition dynamics to the optimal choice with dual rather than single action–outcome asso- ciations. The level of threat did not affect the transition dynamics. Taken together, the data suggested that the strategy of choice behavior was modulated by the infor- mation complexity of the environment..

Gaze likelihood analysis has shown a cascading effect, suggestive of a causal role for the gaze in preference formation during evaluative decision making. According to the gaze bias hypothesis, the gaze serves to build commitment gradually towards a choice. Here, we applied gaze likelihood analysis in a two-choice version of the well- known Iowa Gambling Task. This task requires active learning of the value of different choice options. As such, it does not involve visual preference formation, but choice optimization through learning. In Experiment 1 we asked subjects to choose between two decks with different payoff structures, and to give their responses using mouse clicks. Two groups of subjects were exposed to stable versus varying outcome contingencies. The analysis revealed a pronounced gaze bias towards the chosen stimuli in both groups of subjects, plateauing at more than 400 ms before the choice. The early plateauing suggested that the gaze effect partially reflected eye-hand coordination. In Experiment 2 we asked subjects to give responses using a key press. The results again showed a clear gaze bias towards the chosen deck, this time without any influence from eye-hand coordination. In both experiments, there was a clear gaze bias towards the choice even though the gaze fixations did not narrowly focus on the spatial positions of choice options. Taken together, the data suggested a role for gaze in coarse spatial indexing during non-perceptual decision making..

Here we focus on neural activity that reflects a memory-based code for spatial alternation, independent of current sensory and motor parameters. We recorded multiple single units and local field potentials in the stratum pyramidale of dorsal hippocampal area CA1 while rats performed a delayed spatial-alternation task. This task includes a 1-s fixation in a nose-poke port between selecting alternating reward sites and so provides time-locked enter-and-leave events. At the single-unit level, we concentrated on neurons that were specifically active during the 1-s fixation period, when the rat was ready and waiting for a cue to pursue the task. These neurons showed selective activity as a function of the alternation sequence. We observed a marked shift in the phase timing of the neuronal spikes relative to the theta oscillation, from the theta peak at the beginning of fixation to the theta trough at the end of fixation. The gamma-band local field potential also changed during the fixation period: the high-gamma power (60-90 Hz) decreased and the low-gamma power (30-45 Hz) increased toward the end. These two gamma components were observed at different phases of the ongoing theta oscillation. Taken together, our data suggest a switch in the type of information processing through the fixation period, from externally cued to internally generated..
