Pengertian Psikologi

Psikologi (dari bahasa Yunani Kuno: psyche = jiwa dan logos = kata) dalam arti bebas psikologi adalah ilmu yang mempelajari tentang jiwa/mental. Psikologi tidak mempelajari jiwa/mental itu secara langsung karena sifatnya yang abstrak, tetapi psikologi membatasi pada manifestasi dan ekspresi dari jiwa/mental tersebut yakni berupa tingkah laku dan proses atau kegiatannya, sehingga Psikologi dapat didefinisikan sebagai ilmu pengetahuan yang mempelajari tingkah laku dan proses mental

Sejarah Psikologi

lambang-Psikologi-Trisula

Psikologi adalah ilmu yang tergolong muda (sekitar akhir 1800an.) Tetapi, manusia di sepanjang sejarah telah memperhatikan masalah psikologi. Seperti filsuf yunani terutama Plato dan Aristoteles. Setelah itu St. Augustine (354-430) dianggap tokoh besar dalam psikologi modern karena perhatiannya pada intropeksi dan keingintahuannya tentang fenomena psikologi. Descartes (1596-1650) mengajukan teori bahwa hewan adalah mesin yang dapat dipelajari sebagaimana mesin lainnya.

Ia juga memperkenalkan konsep kerja refleks. Banyak ahli filsafat terkenal lain dalam abad tujuh belas dan delapan belas—Leibnits, Hobbes, Locke, Kant, dan Hume—memberikan sumbangan dalam bidang psikologi. Pada waktu itu psikologi masih berbentuk wacana belum menjadi ilmu pengetahuan.

Psikologi adalah ilmu pengetahuan yang mempelajari perilaku manusia dan proses mental. Psikologi merupakan cabang ilmu yang masih muda atau remaja. Sebab, pada awalnya psikologi merupakan bagian dari ilmu filsafat tentang jiwa manusia. Menurut plato, psikologi berarti ilmu pengetahuan yang mempelajari sifat, hakikat, dan hidup jiwa manusia (psyche = jiwa ; logos = ilmu pengetahuan).

Jiwa secara harfiah berasal dari perkataan sansekerta JIV, yang berarti lembaga hidup (levensbeginsel), atau daya hidup (levenscracht). Oleh karena jiwa itu merupakan pengertian yang abstrak, tidak bisa dilihat dan belum bisa diungkapkan secara lengkap dan jelas, maka orang lebih cenderung mempelajari “jiwa yang memateri” atau gejala “jiwa yang meraga/menjasmani”, yaitu bentuk tingkah laku manusia (segala aktivitas, perbuatan, penampilan diri) sepanjang hidupnya. Oleh karena itu, psikologi butuh berabad-abad lamanya untuk memisahkan diri dari ilmu filsafat.

Perkataan tingkah laku/perbuatan mempunyai pengertian yang luas sekali. Yaitu tidak hanya mencakup kegiatan motoris saja seperti berbicara, berjalan, berlari-lari, berolah-raga, bergerak dan lain-lain, akan tetapi juga membahas macam-macam fungsi seperti melihat, mendengar, mengingat, berpikir, fantasi, pengenalan kembali, penampilan emosi-emosi dalan bentuk tangis, senyum dan lai-lain.

Kegiatan berpikir dan berjalan adalah sebuah kegiatan yang aktif. Setiap penampilan dari kehidupan bisa disebut sebagai aktivitas. Seseorang yang diam dan mendengarkan musik atau tengah melihat televisi tidak bisa dikatakan pasif. Maka situasi dimana sama sekali sudah tidak ada unsur keaktifan, disebut dengan mati.

Pada pokoknya, psikologi itu menyibukkan diri dengan masalah kegiatan psikis, seperti berpikir, belajar, menanggapi, mencinta, membenci dan lain-lain. Macam-macam kegiatan psikis pada umumnya dibagi menjadi 4 kategori, yaitu: 1) pengenalan atau kognisi, 2) perasaan atau emosi, 3) kemauan atau konasi, 4) gejala campuran.

Namun hendaknya jangan dilupakan, bahwa setiap aktivitas psikis/jiwani itu pada waktu yang sama juga merupakan aktifitas fisik/jasmani. Pada semua kegiatan jasmaniah kita, otak dan perasaan selalu ikut berperan ; juga alat indera dan otot-otot ikut mengambil bagian didalamnya.

Penyelidikan terhadap organ-organ manusia digolongkan dalam ilmu fisiologi. Yaitu meneliti peranan setiap organ dalam fungsi-fungsi kehidupan seperti meneliti segala sesuatu tentang mata, ketika subyek bisa melihat dan juga meneliti pengaruh kerja otak untuk mengkoordinir semua perbuatan individu guna menyesuaikan dengan lingkungnnya. Jika fungsi segenap organ dan tingkah laku banyak dijelaskan oleh fisiologi, maka masih perlukah bidang keilmuan psikologi?

Fisiologi memberikan penjelasan macam-macam tingkah laku lahiriah yang menjasmani sifatnya. Sedang manusia merupakan suatu totalitas jasmaniah rokhani. Semua bentuk dorongan dan impuls dalam diri manusia yang menyebabkan timbulnya macam-macam aktifitas fisik dan psikis, dijelaskan oleh psikologi. Misalnya, jika seseorang menaruh rasa semangat yang tinggi , ketika ia mengahadapi suatu masalah tertentu maka ia akan menaggapi masalah itu dengan semangat untuk menyelesaikannya.

* Menurut Crow & Crow :
Pschycology is the study of human behavior and human relationship. (Psikologi ialah tingkah laku manusia, yakni interaksi manusia dengan dunia sekitarnya, baik berupa manusia lain (human relationship) maupun bukan manusia: hewan, iklim, kebudayaan, dan sebagainya.

* Menurut Sartain :
Psychology is the scientific study of the behavior of living organism,with especial attention given to human behavior. (Psikologi adalah ilmu yang mempelajari tingkah laku organisme yang hidup, terutama tingkah laku manusia).

* Menurut Bruno (1987) :
Pengertian Psikologi dibagi dalam tiga bagian, yaitu: Pertama, psikologi adalah studi (penyelidikan) mengenai “ruh”. Kedua, psikologi adalah ilmu pengetahuan mengenai “kehidup mental”. Ketiga, psikologi adalah ilmu pengetahuan mengenai “tingkah laku” organisme.

* Menurut Chaplin (1972) dalam Dictionary of psychology
Psikologi ialah ilmu pengetahuan mengenai perilaku manusia dan hewan.

*Ensiklopedia Pendidikan, Poerbakawatja dan Harahap (1981)
Psikologi sebagai cabang ilmu pengetahuan yang mengadakan penyelidikan atas gejala-gejala dan kegiatan – kegiatan jiwa.

* Menurut Richard Mayer (1981) :
Psikologi merupakan analisi mengenai proses mental dan struktur daya ingat untuk memahami perilaku manusia.
