Extroversion reflects the amount and intensity of relationships of individuals with their environment and refers to the tendency to contact the environment with energy, spirit, enthusiasm, trust and positive experiences (Rolland, 2002, p.8). Extroverted individuals tend to be energetic, enthusiastic, and ambitious (Raja & Johns, 2004). Extroverts are associated with both social and human interactions (Langelaan, Bakker, Doornen, & Schaufeli, 2006, p.525). Highly extroverted individuals are engaging in online shopping activities because it is cruical for them to share and receive information of shopping experiences on digital platforms (Wolfinbarger & Gilly, 2001, p.36). Thoman et al. (2007) states that sharing on the virtual platform is consistent with social motivation. Boedeker, M. (1995) stated in his study that there is a positive correlation between consumers who shop for entertainment and their optimum stimulation level. The optimum stimulation level in extroverted personalities is higher than those with introverted personalities (Ludvigh & Happ, 1974, p. 360). People with high extroversion are expected to believe they have sufficient competence to provide online reviews (Picazo-Vela, Chou, Melcher & Pearson, 2010, p. 688).
Accordingly, H1 hypothesis is as following:
H1: Extroversion has a significant effect on optimum stimulation level.
Online consumers with low arousal levels prefer normal and easy accessible websites that they are familiar with. Individuals with a high arousal level prefer extraordinary websites for their originality and innovativeness because they need to be stimulated and they look for different stimuli (Dhar & Jha, 2014). When the website is quite entertaining (3D pictures, music, colors, etc.), arousal will increase for visitors with high arousal levels (Richard & Chebat, 2016, p. 4–5). Additionally, very low and very high levels of arousal creates negative hedonic tone in individuals. Positive hedonic tone developing in individuals moderate only with sensory stimulation (Ludvigh & Happ, 1974, p. 360).
Some individuals prefer silent settings, while others actively seek to increase their arousal by selecting active, new, complex or unpredictable settings (Raju, 1980, pp. 272–273). Individuals with high arousal levels improve their flow state in their interactions with computer-mediated environments, while individuals with low arousal levels experience anxiety in their interactions with computer-mediated environments (Novak & Hoffman, 1996, p.61). When individuals with high arousal levels are motivated by acquiring information and curiosity, they seek more information than the ones with low arousal levels (Steenkamp & Baumgartner, 1992, p. 434). He et all. (2017) suggested that inquisitive responses may be present for individuals with both high and low arousal levels, but individuals with high arousal levels seek information because they want to search sites they do not know. On the other hand, individuals with low arousal level seek information to reduce the risks presented by foreign websites (Richard & Chebat, 2016, p.4).
According to the discussions above, this research, H2 hypothesis is as follows:
H2: Optimum stimulation level has a significant effect on exploratory information seeking.
Consumers seek information even if they do not buy anything. (Smith, & Sivakumar, 2004, p. 1201). People who seek exploratory information do not pay much attention to the ease of use or reliability of technological products. These people have a high desire and motivation to try technological products (Dabholkar & Bagozzi, 2002, p. 187). Searching information about products on the internet affects the purchasing intentions of consumers (Moe, 2003). Therefore, the services and campaigns offered on websites affect the consumers' intention to search for new things and also their purchase intentions (Tsao & Chang, 2010, p.1802–1803). Some interactions for searching exploratory information on the internet may be more fun (Smith & Sivakumar, 2004)
Although diversity research is limited on online research, the search for diversity or diverse behavior result from interpersonal goals (McAlister & Pessemier, 1982, p.314). Consumer behavior research has associated consumers' search for diversity with the presence of an ideal stimulation level as a personal trait for innovation, complexity, or change (Mahatanankoon, 2007; Gu et al., 2018). After all, consumer arousal levels determine the degree of exploratory purchasing tendencies and diversity seeking behaviors in situations such as shopping (Raju, 1980, p. 276; Menon and Kahn, 1995, p. 285) The search for diversity in the context of online shopping can increase online store comparison behavior; therefore, the search for diversity is seen as an important motivation in the online context (Rohm, & Swaminathan, 2004, p. 750).
Environmental psychology proposed by Mehrabian and Russell (1974) deals with environmental stimuli. The online retail environment does not have some of the traditional dimensions such as ambient temperature, odor, texture. In the context of online retail, visual design emerges consumers' spending long time on websites and increasing intention in their purchases (Koo & Ju, 2010, p. 195). Exploratory behavior is related to the amount of time that an individual uses a computer, and exploratory use causes spending longer hours on internet (Ghani & Deshpande, 1994, p. 383). Justified action and planned behavior theories argue that the intention to perform a certain behaviour in information technologies will lead to its actual behaviour (Korzaan, 2003, p.26–27)
Consumers who are seeking for exploratory information like not only talking their consumption experiences but also following advertisements and promotional activities (Baumgartner & Steenkamp, 1996). Ort and Bourrain (2005) pointed out that the stimulus that triggers specific behavior stemming from curiosity is unique and that exploratory information seeking behavior includes interpersonal communication and exchange dimensions. They stated that the multifaceted behavior resulting from curiosity was affected by stimuli. According to Hanna and Wagle (1988), highly aroused consumers are more exposed to mass media. Hanna and Wagle (1988) also stated that consumers with a high level of stimulation are more innovative than low aroused consumers for changing brands and approaching new products. Doing research on the internet affects the purchasing intention of consumers (Moe, 2003). Therefore, promotional activities and the design of websites of online stores affect purchase intention of consumers (Tsao & Chang, 2010, p. 1802–1803). Maignan and Lukas (1997) stated that internet helps to support pre-purchase phase, as it helps customers compare different options. Dickson (2000) states that it will not be possible for consumers to discover their interests without the internet. Kwak et al. (2002) found that consumers looking for product information online are more likely to purchase (Aljukhadar & Senecal, 2011, p. 423). Consumers with a high level of opinion seeking behaviour tend to search for more information and advice from others during a purchase decision process (Flynn et al. 1996).
Accordingly, this research’s, H3 hypothesis is as follows.
H3: Exploratory information seeking has a significant impact on online purchase intention.
