Testing of behavior bias

This study aims to (i) test the behavior bias of gamblers fallacy occurs at the time of uptrend and downtrend conditions; (ii) test the behavior bias of halo effect occurs at the time of uptrend and downtrend conditions; and (iii) test the behavior bias of familiarity effect occurs at the time of uptrend and downtrend conditions. The number of samples in the study was as many as 41 people. The test equipment used is One-Sample t-Test and Paired t-Test by using statistical package for social scientists (SPSS) as a static test tool. The results of this study show that: (i) Gamblers' fallacy that occurs when the uptrend condition is greater than when the condition is downtrend; (ii) Halo effect that occurs when the uptrend condition is greater than when the downtrend condition; (iii) Familiarity effect that occurs when the uptrend condition is greater than when the downtrend condition.

The influence of L1 translation familiarity on the acquisition of L2 Chinese antonyms

As a partial replication of Tagashira, Kida, and Hoshino (2010), the present study examined first language (L1) translation familiarity effect on second language (L2) antonym acquisition among English-speaking intermediate-level Chinese learners. Fifteen students learned 15 antonymous pairs with familiar or unfamiliar L1 translations and completed two multiple-choice posttests. Their learning strategies were also collected. Results showed (a) a delayed L1 familiarity effect, (b) better retention and lower interference of L2 pairs with familiar L1 translations, (c) low retention of L2 pairs with unfamiliar L1 translations for both words, and (d) more orthographic elaboration strategies employed. The findings suggest that L2 instructors present antonyms in pairs, avoid providing a single, unfamiliar L1 translation, and encourage the use of orthographic elaboration strategies.

Two Factors in Face Recognition: Whether You Know the Person’s Face and Whether You Share the Person’s Race

One of the best-known phenomena in face recognition is the other-race effect, the observation that own-race faces are better remembered than other-race faces. However, previous studies have not put the magnitude of other-race effect in the context of other influences on face recognition. Here, we compared the effects of (a) a race manipulation (own-race/other-race face) and (b) a familiarity manipulation (familiar/unfamiliar face) in a 2 × 2 factorial design. We found that the familiarity effect was several times larger than the race effect in all performance measures. However, participants expected race to have a larger effect on others than it actually did. Face recognition accuracy depends much more on whether you know the person’s face than whether you share the same race.

Target familiarity and visual working memory do not influence familiarity effect in visual search

Familiarity effect refers to the phenomenon that searching for a novel target among familiar distractors is more efficient than that searching for a familiar target among novel distractors. While the familiarity of distractors is considered as a key role on familiarity effect, the familiarity of targets contribute to this asymmetric visual search is unclear. The present study investigated how target familiarity influences visual search efficiency from the perspective of perceptual load. Experiment 1 using two similar Chinese characters (“甲” and “由”) suggested that searching for a familiar target from familiar distractors is an inefficient search process in Chinese context. Experiment 2 adopted a dual-task paradigm with a visual working memory task to increase the perceptual load and attempt to affect the efficiency of searching a novel target (mirrored “舌”) from familiar distractors (“舌”). Results demonstrated no difference in the search efficiency between single and dual-task conditions. The present study suggests that the familiarity of target does not influence the search efficiency with familiar distractors when involving semantic processing of Chinese characters. Additionally, the interference of extra working memory load would not impair the efficiency of searching target among familiar distractors, supporting the critical effect of distractor familiarity on the efficiency of visual search.

The Effect of Efficient Market Hypothesis, Gambler's Fallacy, Familiarity Effect, Risk Perception, and Economic Factors on Investment Decisions (Studies on Capital Market Investors in Medan City)

This study aims to examine the effect of the efficient market hypothesis, gambler's fallacy, familiarity effect, risk perception, and economic factors on investment decisions. This research is quantitative research with a descriptive approach. The population in this study were all capital market investors in Medan City. Determination of the research sample carries out by using judgment sampling technique and Malhotra theory so that 270 samples obtain. Data analysis using multiple linear regression analysis. The results of the multiple linear regression analysis showed that the efficient market hypothesis, gambler's fallacy, familiarity effect, risk perception, and economic factors partially had a positive and significant impact on investment decision making. Other results, the efficient market hypothesis, gambler's fallacy, familiarity effect, risk perception, and economic factors simultaneously have a positive and significant impact on investment decision making.

Home Advantage in Skeleton: Familiarity versus Crowd Support

The paper investigates home advantages in skeleton. Our study broadens home advantage literature by providing models and estimation strategy applicable to other individual sports with tracks or courses such as biathlon, cross country skiing, etc. We identified two sources of advantages: support from the crowd; familiarity with the track. In the Olympics and the World Championships, home advantage leads to about a 0.510% improvement in performance on average, of which 0.110%-points are due to crowd support and 0.401%-points due to familiarity. Out-contribution of familiarity effect is common in all six major skeleton series.

The sibling familiarity effect: Is within-person facial variability shared across siblings?

Humans are experts at familiar face recognition, but poor at unfamiliar face recognition. Familiarity is created when a face is encountered across varied conditions, but the way in which a person’s appearance varies is identity-specific, so familiarity with one identity does not benefit recognition of other individuals. However, the faces of biological siblings share structural similarities, so we explored whether the benefits of familiarity are shared across siblings. Results show that familiarity with one half of a sibling pair improves kin detection (experiment 1), and that unfamiliar face matching is more accurate when targets are the siblings of familiar vs unfamiliar individuals (experiment 2). PCA applied to facial images of celebrities and their siblings demonstrates that, for shape, faces are generally better reconstructed in the principal components of a same-sex sibling than those of an unrelated individual. When we encounter the unfamiliar sibling of someone we already know, our pre-existing representation of their familiar relation may usefully inform processing of the unfamiliar face. This can benefit both kin detection and identity processing, but the benefits are constrained by the degree to which facial variability is shared.
